Zusammenhänge zwischen der Struktur und dem Massenspektrum organischer Verbindungen
Authors: Spiteller G. , Spiteller‐Friedmann Margot
Published: July 2007

Unsere Kenntnisse über Die Zusammenhänge zwischen der Struktur und dem Massenspektrum organischer Verbindungen haben sich in den letzten Jahren sehr erweitert. Es wird daher möglich, den die Bruchstückbildung beherrschenden Einfluß bestimmter Substituenten durch einfache chemische Reaktionen soweit zu verändern, daß völlig andere Hauptspaltungsreaktionen als beim Ausgangsmaterial ablaufen. Durch diese Lenkung des massenspektrometrischen Abbaus in Kombination mit chemischen Mikroreaktionen wird die Lösung komplizierter Strukturprobleme oft mit geringstem Zeit‐ und Materialaufwand möglich. Ein Beispiel für die Änderung des Spaltungsbildes durch eine einfache chemische Umsetzung wird im Zusammenhang mit der Besprechung der Aufklärung der Pleiocarpamin‐Struktur diskutiert.
Gleichgewichts‐ und Transporteigenschaften konzentrierter Elektrolytlösungen
Authors: Haase R.
Published: July 2007

Nach einem historischen Rückblick werden folgende Probleme bei konzentrierten Lösungen von Elektrolyten mit zwei ionischen Bestandteilen behandelt: die allgemeine thermodynamische Charakterisierung, das Dissoziationsgleichgewicht, die Entmischung, die analytische Darstellung der thermodynamischen Funktionen im gesamten Konzentrationsbereich sowie generelle Gesetzmäßigkeiten der Elektrizitätsleitung, Diffusion und Sedimentation. Es werden Formeln aufgestellt, die für beliebige Konzentrationen gelten; bekannte Beziehungen für verdünnte Elektrolytlösungen ergeben sich daraus als Spezialfälle. — Numerische Beispiele, meist mit neuesten Meßdaten, erläutern die Ausführungen über konzentrierte Elektrolytlösungen.
Die Struktur der Zucker‐phenylosazone
Authors: Mester L.
Published: July 2007

Die offenkettige Chelatstruktur, die zuerst von Fieser und Fieser für die Zuckerosazone vorgeschlagen wurde, konnte in den letzten Jahren durch chemische Untersuchungen, Röntgenstrukturanalyse und NMR‐Spektroskopie bestätigt werden. Diese Arbeiten führten zu einer Verfeinerung der vorgeschlagenen Struktur im Sinne eines quasiaromatischen Chelatringes.

Authors: Seel F.
Published: July 2007

Durch Umsetzung von salpetriger Säure, Distickstofftrioxyd, Distickstofftetroxyd und Nitrosylverbindungen mit flüssigem Fluorwasserstoff entstehen unerwartet hoch siedende, unverändert destillierbare Lösungen, welche Nitrosylfluorid in Form ungewöhnlich beständiger elektrolytisch dissoziierter Fluorwasserstoff‐Solvate, enthalten. Das reine fluorwasserstoff‐solvatisierte Nitrosylfluorid ist ein neues wertvolles Reagens der Fluorchemie, das mit vielen Elementen und Verbindungen zu präparativ interessanten Fluorverbindungen reagiert.

Authors: Witt H. T. , Rumberg B. , Schmidt‐Mende P. , Siggel U. , Skerra B. , Vater J. , Weikard J.
Published: July 2007

Direkte Informationen über den Primärprozeß der Photosynthese gewinnt man durch Messung der sehr kurzlebigen Primär‐ und Zwischenprodukte mit Hilfe 1. der Blitzlichtphotometrie, 2. der periodischen Blitzlichtphotometrie und 3. der Blitzlichtmanometrie. — Die Analyse des Primärprozesses mit Hilfe dieser Methoden an normalen und durch chemische oder physikalische Eingriffe veränderten Pflanzenzellen und Chloroplasten ermöglichte die Aufstellung eines Reaktionsschemas für den Elektronentransport in der Photosynthese.
Sequenzverteilung in Copolymeren Untersuchung der physikalischen Eigenschaften
Authors: Harwood H. J.
Published: July 2007

Die physikalischen Eigenschaften von Copolymeren sind durch ihre Zusammensetzungen und durch die Verteilung der Monomersequenzen bestimmt. In einigen Fällen kann die Sequenzverteilung aus den physikalischen Eigenschaften des Copolymeren abgeleitet werden. Dies ist relativ einfach, wenn die Berechnungen auf „Blockzahlen”︁ (run numbers) basieren.
Grundlagen und Entwicklung des Verfahrens zur Trennung der Elemente Zirkonium und Hafnium durch Verteilen ihrer Thiocyanate
Authors: Mit Werner Fischer Gemeinsam , Deierling B. , Heitsch H. , Otto G. , Pohlmann H.‐P. , Reinhardt K.
Published: July 2007

Die Verteilungsgleichgewichte von Zirkonium‐ und Hafniumthiocyanat zwischen Wasser und Methyl‐isobutyl‐keton werden in Abhängigkeit von verschiedenen Versuchsbedingungen untersucht. Da das System in extremer Weise vom Nernstschen Verteilungssatz abweicht, ist eine weitgehende Trennung der beiden Elemente durch vielstufige Verteilung in einem Arbeitsgang nicht ohne weiteres möglich. Durch geeignete Zusätze und eine neue Art der Phasenführung gelang es jedoch, ein kontinuierliches Verfahren für präparative und technische Zwecke zu entwickeln, mit dem sich mit 23 Mischer‐Absetzern aus einem Zirkonium‐Hafnium‐Gemisch (Hafnium‐Gehalt: 1 bis 2%) ein ZrO2‐Präparat mit < 10 ppm HfO2 und gleichzeitig ein HfO2‐Präparat mit 0,3% ZrO2 gewinnen läßt.
Über Verbindungen des Phosphors mit Silicium und Aluminium
Authors: Fritz G. , Mit Nach Untersuchungen , Becker G. , Poppenburg G. , Rocholl M. , Trenczeck G.
Published: July 2007

Es werden Bildung und Eigenschaften der Silicium‐Phosphor‐ und Aluminium‐Phosphor‐Verbindungen beschrieben. Silylphosphine werden solvolytisch von H2O, C2H5OH, NH3, Halogenwasserstoffen, C2H5J und Borhalogeniden an der Si–P‐Bindung gespalten, wobei der Spaltung die Bildung einer Additionsverbindung vorgelagert sein kann. Die bei der Umsetzung von Halogensilanen mit LiPEt2[1] stark hervortretenden Nebenreaktionen (Bildung von Et2P‐PEt2, HPEt2, Si‐reichen Rückständen) sind auf überschüssiges LiPEt2 im Reaktionsgemisch zurückzuführen. – Die Umsetzung von LiPEt2 mit AlCl3, AlHCl2 und AlH2Cl führt zu definierten Aluminium‐Phosphor‐Verbindungen, wenn auf ein Al‐Atom nur eine PEt2‐Gruppe kommt, z. B. in (Cl2Al‐PEt2)3 und (H2Al‐PEt2)3, oder wenn sich mit überschüssigem LiPEt2 Salze wie Li [Al(PEt2)4] und Li[AlH2(PEt2)2] bilden können.
Die Bedeutung von Mutanten bei Enterobacteriaceen für die chemische Erforschung ihrer Zellwand‐Polysaccharide
Authors: Lüderitz O. , Westphal O.
Published: July 2007

Enterobacteriaceen bilden als äußere Zelloberfläche eine Zellwand, die aus einer rigiden Struktur (Murein) besteht, auf welche Protein, Lipoid und Polysaccharid aufgelagert sind. Bei den bakteriellen Wildformen (S‐Formen) ist das Polysaccharid species‐spezifisch und Träger der serologisch determinanten Gruppen des jeweiligen O‐Antigens. Es handelt sich um Heteropolysaccharide, an deren Aufbau bis zu acht verschiedene Monosaccharide beteiligt sein können. Gebunden an Lipoid A, stellen die Lipopolysaccharide der Zellwände die Endotoxine dieser Bakterien dar. – In den letzten Jahren ist die Struktur der enterobakteriellen Zellwand‐Polysaccharide durch chemische, immunchemische, biochemische und genetische Untersuchungen besonders bei Salmonellen weitgehend aufgeklärt worden. Sie sind aus zwei Anteilen aufgebaut: einem allen Species gemeinsamen Kern‐ oder Basal‐Polysaccharid, an welches (bei den S‐Formen) längere species‐spezifische Seitenketten gebunden sind, die aus sich wiederholenden Oligosaccharid‐Einheiten bestehen. – Durch spontane S → R‐Mutation entstehen R‐Formen, welche sich als Verlust‐Mutanten der Wildformen in Bezug auf die Biosynthese des kompletten Zellwand‐Polysaccharids erwiesen haben. Gegenüber der Vielfalt an serologischen Spezifitäten der S‐Formen findet man bei R‐Formen nur einige wenige Serotypen (RI, RII u. a.) Die R‐Polysaccharide entsprechen Zwischenstufen in der Biosynthese des Polysaccharids der Wildform, und die S → R‐Mutation führt jeweils zum Verlust (oder zur Blockierung) eines am Aufbau des S‐Polysaccharids beteiligten Enzyms (Transferase, Synthetase). Neuerdings konnten viele bisher unbekannte Verlust‐Mutanten isoliert und analysiert werden, wodurch zahlreiche biosynthetische Zwischenstufen des Zellwand‐Polysaccharids, z.B. von Salmonella minnesota, der direkten Analyse zugänglich wurden. – Nach diesen Untersuchungen bestehen die Zellwand‐Polysaccharide der Salmonellen aus einer Polyheptosephosphat‐Grundkette, welche über Ketodesoxyoctonsäure (KDO) an Lipoid A gebunden ist. An die Grundkette sind Pentasaccharid‐Einheiten von magnified image gebunden (RII‐Struktur). Alle übrigen R‐Formen sind strukturell Verlust‐Mutanten von RII. In den kompletten Polysacchariden der Salmonella‐S‐Formen sind an das terminale N‐Acetylglucosamin der RII‐Struktur die sich wiederholenden Oligosaccharid‐Einheiten der spezifischen Seitenketten gebunden.
Austauschgleichgewichte und die Analyse von Gemischen labiler Verbindungen
Authors: van Wazer J. R. , Moedritzer K.
Published: July 2007

Die Bedeutung chemischer Gleichgewichte für die anorganische Strukturchemie wird nachgewiesen, und es wird gezeigt, wie sich Art und Ausbeute der verschiedenen Moleküle quantitativ erfassen lassen. Da kinetisch kontrollierte Reaktionen in der organischen Chemie eine große Rolle spielen, und da die Chemie der Kohlenstoffverbindungen der am weitesten fortgeschrittene Zweig der allgemeinen und beschreibenden Chemie ist, hat man in der anorganischen Chemie den Wert von Reaktionsmechanismen oft überbetont und dabei übersehen, wie nützlich thermodynamische Untersuchungen zur Behandlung äquilibrierender Systeme sind. Die vorliegende Arbeit zeigt in großen Zügen die allgemeinen Regeln, mit denen sich die in Verbindungsfamilien auftretenden Gleichgewichte beschreiben lassen.
Komplexbildung und Blütenfarben
Authors: Bayer Ernst , Egeter H. , Fink A. , Nether K. , Wegmann K.
Published: July 2007

Der Farbstoff der blauen Kornblume, Protocyanin, ist ein Komplex von hohem Molekulargewicht. Eisen(III)‐ und Aluminium‐Ionen bilden mit der Anhydrobase des Cyanins tiefblaue Chelate, die im physiologischen pH‐Bereich beständig sind. Solche Komplexe sind auch synthetisch hergestellt worden. Alkalisalze spielen bei blauen Blütenfarben keine Rolle. Die Bildung blauer Komplexe kann durch Markierung der Metallionen mit stärkeren Komplexbildnern, z.B. Flavonolen, verhindert werden. Auf der Grundlage der Komplexbildung von Anthocyanen läßt sich die Variation der Blütenfarben in breitem Umfang erklären. Bei Delphinidinglykosiden ist die Farbbase oder Anhydrobase auch bei schwach saurem pH beständig.
Chemie und Biochemie des Insulins
Authors: Klostermeyer H. , Humbel R. E.
Published: July 2007

Das Eiweißhormon Insulin ist im Tierreich weitverbreitet, seine Aminosäurezusammensetzung ist bei gleicher biologischer Wirksamkeit sehr unterschiedlich. – Insulin besteht aus zwei Polypeptidketten, die durch drei Cystinreste zu einem bicyclischen System aus 20 und 85 Ringgliedern verknüpft sind. – Das Protein kristallisiert mit Fremdionen in verschiedenen Formen. In Lösungen bildet Insulin gewöhnlich Aggregate aus 2 n Molekülen. – Das Hormon kann aus den getrennten Polypeptidketten regeneriert werden. Die Totalsynthese erfolgte analog aus synthetisierten Peptidketten. – Bei der Biosynthese wird Insulin anscheinend auch aus den beiden separat entstandenen Ketten zusammengefügt. – Im Organismus fördert Insulin den Aufbau von Glykogen, Fett und Protein; Insulinmangel äußert sich im Anstieg des Blutzuckers. Der eigentliche Wirkungsmechanismus des Hormons ist immer noch unbekannt. – Ein spezifisches Wirkzentrum konnte im Insulinmolekül noch nicht nachgewiesen werden, es enthält mehrere antigene Bereiche.
Isotopeneffekte in der organischen Chemie und Biochemie
Authors: Simon H. , Palm D.
Published: July 2007

Es wird gezeigt, in welchem Maß bei Anwendung der Isotopentechnik mit Isotopeneffekten zu rechnen ist und welche Probleme mit primären und sekundären kinetischen Isotopeneffekten bearbeitet werden. Als Beispiel werden die Untersuchungsergebnisse bei E2‐Reaktionen, speziell beim Hofmann‐Abbau, diskutiert. Danach werden einige „analytische Isotopeneffekte”︁ besprochen. Schließlich werden die Probleme und Aussagemöglichkeiten von Isotopeneffekt‐Studien bei Enzymreaktionen, u.a. die Vor‐ und Nachteile des kompetitiven und nicht kompetitiven Arbeitens, erörtert. Neben einer Zusammenstellung von Isotopeneffekten bei Dehydrogenase‐Reaktionen werden neue Isotopeneffekte, die bei der Dehydrierung T‐markierter Alkohole auftreten, mitgeteilt.

Authors: Dähne S. , Leupold D.
Published: July 2007

In Farbstoffmolekülen, die zwei und mehr Polymethin‐Strukturelemente, oder wenigstens ein Polymethin‐ und ein Polyen‐Strukturelement enthalten, treten in der Regel Kopplungseffekte auf, die das spektroskopische Verhalten und andere physikalisch‐chemische Eigenschaften bestimmen. Mit Hilfe der Kopplungskonzeption können u.a. die Chinonfarbstoffe, die Indigoide und die Indanthrene in ein allgemeines Farbsystem der Polymethine eingeordnet und neue Farbstoffstrukturen vorhergesagt werden.
Chemie stabiler Lithium‐α‐halogenorganyle und Mechanismus carbenoider Reaktionen
Authors: Köbrich G. ,   IN ZUSAMMENARBEIT MIT
Published: July 2007

Vor einigen Jahren fanden wir, daß die als Zwischenprodukte metallorganisch initiierter α‐Eliminierungen postulierten Lithium‐α‐halogenorganyle (Carbenoide) in stabiler Form zugänglich sind. Die vorliegende Arbeit gibt einen Überblick über die Darstellungsmöglichkeiten der Carbenoide und über ihr chemisches Verhalten. Sie vereinen nucleophile und elektrophile Reaktivität, die sich einzeln oder kombiniert zur Synthese recht verschiedenartiger Substanzklassen heranziehen lassen. Ursache für ihre Thermolabilität, die durch das Solvens Tetrahydrofuran erheblich vermindert wird, sind — mit bisher nur einer Ausnahme — elektrophile Folgereaktionen, bei denen offensichtlich keine Carbene als Intermediärprodukte auftreten. Die untersuchten Reaktionen erlauben eine einheitliche mechanistische Interpretation.
The psychophysics of spending
Authors: Christensen Caryn
Published: July 2007

Several theories of decision making are based, in part, upon the principles of psychophysics (Kahneman and Tversky, 1979; Thaler, 1985). For example, due to the psychophysics of quantity, the difference between $10 and $20 seems greater than the difference between $110 and $120. To determine whether psychophysics influences consumers' decisions, subjects in four studies made real or hypothetical purchases. It was predicted that as the size of the purchase increased, subjects would be more willing to buy additional smaller items. Small extra purchases should seem like minor expenditures when they follow larger purchases. Results of the four studies supported our hypothesis. In addition, it was found that subjects responded not only to actual changes in purchase size but also to changes in the presentation or framing of a purchase.
Psychological conceptions of randomness
Authors: Ayton Peter , Hunt Anne J. , Wright George
Published: July 2007

This article presents a critique of the concept of randomness as it occurs in the psychological literature. The first section of our article outlines the significance of a concept of randomness to the process of induction; we need to distinguish random and non‐random events in order to perceive lawful regularities and formulate theories concerning events in the world. Next we evaluate the psychological research that has suggested that human concepts of randomness are not normative. We argue that, because the tasks set to experimental subjects are logically problematic, observed biases may be an artifact of the experimental situation and that even if such biases do generalise they may not have pejorative implications for induction in the real world. Thirdly we investigate the statistical methodology utilised in tests for randomness and find it riddled with paradox. In a fourth section we find various branches of scientific endeavour that are stymied by the problems posed by randomness. Finally we briefly mention the social significance of randomness and conclude by arguing that such a fundamental concept merits and requires more serious considerations.
Ducking the collection of costly evidence: Motivated use of statistical heuristics
Authors: Sanitioso Rasyid , Kunda Ziva
Published: July 2007

We examined whether motivation affects people's use of statistical heuristics. In two studies, subjects had to decide how many instances to observe before making predictions. Half the subjects were led to believe that the observation of each instance would be relatively high in cost, and half were led to believe that it would be relatively low in cost. In both studies, only subjects for whom evidence collection was relatively high in cost accessed the aggregation principle and came to believe that aggregates afforded greater predictability than did single instances. Their belief that predictability increases sharply with sample size may have allowed these subjects to conclude what they wanted to conclude, namely that smaller samples would suffice for their predictions.
Factors influencing the use of internal summary evaluations versus external information in choice
Authors: Hulland John S. , Kleinmuntz Don N.
Published: July 2007

Decision makers cope with more demanding tasks by shifting their cognitive strategies, balancing effort expenditure against the desire to produce an accurate response. In choice tasks, one method for reducing effort while simultaneously maintaining accuracy is to shift from a reliance on information obtained from the external environment to that retrieved from memory, particularly summary evaluations (i.e. relatively stable evaluative reactions to the overall attractiveness of individual alternatives) acquired from previous decision‐making experience. We examined four factors that should all encourage decision makers to rely to some extent on internal summary evaluations rather than external information search: (1) increased external search costs, (2) greater time pressure, (3) increased incentives to make an accurate choice, and (4) increased levels of prior experience with the choice context. Sixty experimental subjects chose their preferred alternative from a set of women's magazines. Decision processes were inferred from verbal protocols, computer‐generated search records, and decision times. Only increased external search costs led to a greater reliance on summary evaluations. Although increased time pressure, increased incentives, and increased experience with the context did lead to changes in search and evaluation processes, contrary to initial expectations decision makers did not shift to a greater reliance on summary evaluations. These results suggest that while decision makers do sometimes use summary evaluations as a substitute for external search, this is only one of several mechanisms available for effort reduction. Understanding when and where decision makers rely upon summary evaluations probably requires a broader conceptualization of knowledge structures, particularly a consideration of the knowledge that decision makers possess about different choice strategies and their effectiveness.
The judgment‐choice discrepancy: Noncompatibility or restructuring?
Authors: Montgomery Henry , Selart Marcus , Gärling Tommy , Lindberg Erik
Published: July 2007

The study examines the relative merits of a noncompatibility and a restructuring explanation of the recurrent empirical finding that a prominent attribute looms larger in choices than in judgments. Pairs of equally attractive options were presented to 72 undergraduates who were assigned to six conditions in which they performed (1) only preference judgments or choices, (2) preference judgments or choices preceded by judgments of attractiveness of attribute levels, or (3) preference judgments or choices accompanied by think‐aloud reports. The results replicated the prominence effect for choices, but a prominence effect was also found for preference judgments. In accordance with the restructuring explanation, the think‐aloud protocols indicated that options were more often restructured in choices than in preference judgments. However, restructuring could not explain the prominence effect observed for preference judgments. A modified compatibility hypothesis is offered as an alternative explanation.
The limits of anchoring
Authors: Chapman Gretchen B. , Johnson Eric J.
Published: July 2007

Anchoring and adjustment is a pervasive bias in which decision makers are influenced by random or uninformative numbers or starting points. As a means of understanding this effect, we explore two limits on anchoring. In Experiments 1 and 2, implausibly extreme anchors had a proportionally smaller effect than anchors close to the expected value of the lotteries evaluated. In Experiments 2 and 3, anchoring occurred only if the anchor and preference judgment were expressed on the same scale. Incompatible anchors and response modes resulted in no anchoring bias. A confirmatory search mechanism is proposed to account for these results.
Are preference reversals reduced when made explicit?
Authors: Ordóñez Lisa D. , Mellers Barbara A. , Chang Shi‐Jie , Roberts Jordan
Published: July 2007

Previous research has shown that preferences for options, such as gambles, can reverse depending on the response mode. These preference reversals have been demonstrated when tasks were performed sequentially. That is, subjects completed one task before beginning another. In an attempt to eliminate preference reversals, we asked subjects to perform tasks simultaneously. That is, subjects made two types of responses for each pair of gambles before evaluating the next pair. In the condition with no financial incentives, preference reversal rates were slightly reduced. In another condition, subjects were paid for their participation and they were allowed to play a gamble with real monetary compensation. A gamble pair was randomly selected, and if a subject's responses in the two tasks were consistent for that pair, he or she was allowed to play the ‘preferred’ gamble. Otherwise, the experimenter selected the gamble from the pair. With these financial incentives, systematic preference reversals were eliminated for two of the three task combinations. Preference reversals continued to occur for attractiveness ratings versus selling prices, although, even for that pair of tasks, the reversal rate was significantly reduced. For all three task pairs, preference orders from the two tasks appeared to merge into more consistent orders.
