1.2‐Dehydrobenzol
Authors: Wittig G. 
Published: July 2007

AbstractDie Entwicklungslinien der Methodik zur Darstellung von Dehydrobenzol werden umrissen. — Dehydrobenzol zeigt Bereitschaft zur Addition nucleophiler wie elektrophiler Partner. Darüberhinaus erweist sich die Diels‐Alder‐Addition an Diene als wertvolles Syntheseprinzip. Daß tatsächlich Dehydrobenzol in Lösung auftritt, wurde für polare Additionen an 14C‐markierten oder geeignet substituierten Aromaten nachgewiesen, für die Diels‐Alder‐Reaktion gelang dies auf der Basis konkurrierender Additionen. Die bei beiden Reaktionstypen beobachtete Selektivität des Dehydrobenzols kann nicht wesentlich durch Solvatation hervorgerufen sein, da neuerdings das Auftreten von Dehydrobenzol in der Gasphase gesichert wurde, wobei es ähnliche Reaktionen wie in Lösung eingeht.
Valenzisomere aromatischer Systeme
Authors: Van Tamelen E. E. 
Published: July 2007

AbstractZur Klassifizierung von Valenzisomeren wird das Präfix χn vorgeschlagen, wobei n den Unterschied der Ringzahl oder der Anzahl π‐Bindungen bedeutet. Zur χ1‐Reihe gehören z. B. Dewar‐Benzol und 9,10‐Dihydronaphthalin, die auf Grund geometrischer und stereoelektronischer Überlegungen synthetisiert werden konnten. Benzvalen und Prisman sind Vertreter der χ2− bzw. χ3− Reihe.
Verfahren zur Darstellung von Methyl‐Metallverbindungen
Authors: Sundermeyer W. , Verbeek W. 
Published: July 2007

AbstractEin neues Verfahren ermöglicht die Darstellung von Methyl‐Metallverbindungen aus Methylchlorid und den Chloriden der Elemente Bor, Aluminium, Silicium, Zinn, Phosphor, Antimon oder Quecksilber. Geschmolzene Salze werden dabei als Lösungsmittel und darin suspendierte Metalle als Halogenakzeptoren verwendet. Durch Elektrolyse werden die Metalle neben Chlor wiedergewonnen. Das kontinuierlich und quantitativ ablaufende Verfahren ermöglicht die Herstellung solcher technisch wichtiger Methyl‐Metallverbindungen, die mit Hilfe des „Mülheimer Aluminiumalkyl‐Verfahrens”︁ nicht direkt zugänglich sind.
Die Biosynthese der Cyclite
Authors: Kindl H. , Scholda R. , Hoffmann‐Ostenhof O. 
Published: July 2007

AbstractIn letzter Zeit ist es – vor allem mit Hilfe radioaktiv markierter Verbindungen – gelungen, Einblick in die Biosynthese verschiedener Cyclite zu erhalten. Es konnte gezeigt werden, daß für meso‐Inosit, den am weitesten verbreiteten Cyclit, ein wahrscheinlich für alle Organismen gültiger Biosyntheseweg existiert, bei dem durch Ringschluß über die beiden endständigen Kohlenstoffatome von D‐Glucose der Cyclohexanring entsteht. Aus verschiedenen biologischen Materialien können zellfreie Extrakte oder Enzymsysteme hergestellt werden, welche die Überführung von D‐Glucose in meso‐Inosit katalysieren. – Die Biosynthese der anderen Hexahydroxycyclohexane (Inosite) verläuft über meso‐Inosit als Zwischenprodukt; einzelne Teilschritte der Überführung von meso‐Inosit in andere Inosite wurden untersucht.
Die Chemie der α‐Carbonyl‐Azoverbindungen
Authors: Fahr E. , Lind H. 
Published: July 2007

Abstractα‐Carbonyl‐Azoverbindungen wie Azodicarbonsäurediester, Diacyl‐Azoverbindungen und Aryl‐azo‐carbonsäureester sind recht reaktionsfreudige Verbindungen. Sie addieren sich z. B. an Amine, Aromaten, Olefine, CH‐acide Substanzen, Grignard‐ und Diazo‐Verbindungen, Aldehyde, Ketone und Ketene. Dabei sind u. a. Triazane, Hydrazone, Oxadiazolin‐, Azomethin‐imin‐ und Diazetidin‐Derivate zugänglich. α,α'‐Dicarbonyl‐Azoverbindungen gehören zu den besten Dienophilen.
Reaktionen des elementaren Siliciums
Authors: Bonitz E. 
Published: July 2007

AbstractElementares Silicium wird üblicherweise mit gasförmigen Reaktionspartnern „trocken”︁ in der Wirbelschicht oder im Fließbett umgesetzt. Die scheinbare Reaktionsträgheit des gewöhnlichen Siliciums beruht auf einer Oberflächenpassivierung. Nicht passiviertes Silicium reagiert wie stärker elektropositive Elemente. Feinverteiltes Si ist pyrophor und bildet mit vielen Stoffen (z. B. Alkoholen, Wasser, Metall‐ und Organohalogeniden) bereits bei Raumtemperatur Oberflächenverbindungen. – Den „trockenen”︁ Verfahren steht ein neues Suspensionsverfahren gegenüber, bei dem feinverteiltes, aktiviertes Silicium – vorzugsweise in seinen flüssigen Reaktionsprodukten suspendiert, gegebenenfalls in Gegenwart löslicher Katalysatoren – meist mit flüssigen Stoffen und bei höherem Druck umgesetzt wird. Die Reaktionen können in Suspensionen leicht beherrscht werden; das Silicium wird dabei quantitativ verbraucht. Polysilane sind oft die ausschließlichen Primärprodukte, die in homogener flüssiger Phase zu Monosilanen weiterreagieren. Durch Auflösen von gewöhnlichem Silicium beispielsweise in Methanol erhält man glatt Methoxysilane, die an ungesättigte Kohlenwasserstoffe addiert werden können.
Polymere mit Lactongruppen
Authors: Palm R. , Ohse H. , Cherdron H. 
Published: July 2007

AbstractPolymere mit intakten Lactongruppen sind ein neuer Typ von Makromolekülen mit reaktiven Gruppen, die sich durch Polymerisation, Polykondensation und Polyaddition sowie durch Umsetzungen an Makromolekularen selbst relativ einfach darstellen lassen. Insbesondere Polymere mit β‐Lactongruppen sind zahlreichen Additionsreaktionen zugänglich, wobei man u. a. Makromoleküle mit Hydroxycarbonsäure‐ oder Aminocarbonsäuregruppen erhalten kann. Die Umsetzungen gelingen unter milden Bedingungen und sogar in wäßrigem Medium; dabei entstehen häufig wasserlösliche Polymere. Durch Verwendung bi‐ oder oligofunktioneller Additionspartner ist eine Vernetzung bei niedrigen Temperaturen auch aus wäßriger Phase möglich. Polymere mit β‐Lactongruppen eignen sich auch als Basis für Pfropf(co)polymere; je nachdem, ob man monomere Lactone oder monomere Epoxide einsetzt, lassen sich Polyester‐ oder Polyätherzweige aufpfropfen.
Selecting K of N alternatives
Authors: Barron F. Hutton 
Published: July 2007

AbstractIn some decision contexts (e.g. graduate admissions) the task to select a subset of k distinct alternatives from among the N > k > 1 options available. For moderate values of N and k, the number of possible subsets of size k becomes quite large. Assuming alternatives are evaluated using consistent, though not explicit weights, selecting k, rather than 1, empirically excludes a substantial proportion (more than 80%) of the subsets; unfortunately to the unaided decision maker it is not obvious which subsets should be excluded. The tendency of subjects to select excludable subsets can be called an ‘infeasibility’ bias. The experimental evidence surprisingly shows no ‘infeasibility’ bias, as subjects overwhelmingly chose non‐excluded selections.
On luck and chance: Need for control as a mediator of the attribution of events to luck
Authors: Friedland Nehemia 
Published: July 2007

AbstractChance and luck are regarded as two distinct causal agents that effect different results. Whereas chance is deemed utterly uncontrollable, luck elicits, at the very least, an illusion of control. Hence, need for control might be a decisive factor in determining whether an event is attributed to chance or to luck. More specifically, the greater is a person's need for control, the stronger would be that person's tendency to attribute events to luck. This proposition, along with its implications concerning effects of luck attributions on decision making, were tested in three experiments. The results showed that situational circumstances and personality dispositions that heighten individuals' need for control strengthen their tendency to attribute events and outcomes to luck. The results showed, further, that such attributions can affect the process of decision making.
