Sulfobutyl Ether‐β‐Cyclodextrins: Promising Supramolecular Carriers for Aqueous Organometallic Catalysis
Authors: Blach Philippe , Landy David , Fourmentin Sophie , Surpateanu Gheorghe , Bricout Hervé , Ponchel Anne , Hapiot Frédéric , Monflier Eric
Published: July 2005

The potentialities of sulfobutyl ether‐β‐CDs derivatives as supramolecular carrier in a biphasic Tsuji–Trost reaction catalyzed by a water‐soluble palladium complex of trisulfonated triphenylphosphine have been investigated. The efficiency of these cyclodextrins (CDs) strongly depends on the average molar substitution degree of cyclodextrin and the highest rate enhancements were obtained with cyclodextrins containing about 7 sulfobutyl ether groups. This result was attributed to the absence of a strong interaction between this cyclodextrin and the trisulfonated triphenylphosphine used to dissolve the catalyst in the aqueous phase and to the presence of an extended hydrophobic cavity allowing a better molecular recognition between the substrate and the cyclodextrin. This constitutes the first example of a non‐interacting β‐cyclodextrin/phosphine couple with high catalytic activities.
Bulky Achiral Triarylphosphines Mimic BINAP in Ru(II)‐ Catalyzed Asymmetric Hydrogenation of Ketones
Authors: Jing Qing , Zhang Xue , Sun Jie , Ding Kuiling
Published: July 2005

In the present work, we report on catalysis of the enantioselective hydrogenation of ketones with Ru(II) complexes composed of cheap achiral monodentate phosphine ligands in combination with an enantiopure 1,2‐diamine, affording a variety of optically active secondary alcohols with high efficiency and enantioselectivity. The steric impact of achiral monophosphine ligands in Ru complexes was found to be a critical factor for the high enantioselectivity of the reaction. This finding throws some light on a long‐standing challenge, the high cost of chiral bisphosphine ligands, associated with an industrial application of the asymmetric hydrogenation of ketones.
Cyanide‐Catalyzed Additions of Acyl Phosphonates to Aldehydes: A New Acyl Donor for Benzoin‐Type Reactions
Authors: Bausch Cory C. , Johnson Jeffrey S.
Published: July 2005

Acyl phosphonates have been utilized as new acyl donors for cyanide‐catalyzed benzoin‐type reactions. Cyanation of acyl phosphonates, followed by a [1,2]‐phosphoryl migration generates the active acyl anion intermediate. The presumed (cyano)phosphate anion reacts with a variety of aryl aldehydes to yield phosphate ester‐protected, unsymmetrical benzoins in good to excellent yields. The unsymmetrical benzoin product can be obtained after deprotection of the phosphate ester with an aqueous amine solution.
New numerical method for solving the dynamic population balance equations
Authors: Hu Q. , Rohani S. , Jutan A.
Published: July 2005

A new numerical scheme is proposed for solving general dynamic population balance equations (PBE). The PBE considered can simultaneously include the kinetic processes of nucleation, growth, aggregation and breakage. Using the features of population balance, this method converts the PBE into a succession of algebraic equations which can be solved easily and accurately. The new method is free from stability and dispersion problems of general numerical techniques. Some benchmark problems with analytic solutions were tested. In all cases tested this method gave accurate results with very few computational requirements. For nucleation and size‐independent growth without aggregation and breakage, the numerical method gives exactly the same result as analytic solution. © 2005 American Institute of Chemical Engineers AIChE J, 2005
Microsecond Protein Dynamics Measured by 13Cα Rotating‐Frame Spin Relaxation
Authors: Lundström Patrik , Akke Mikael
Published: July 2005

NMR spin relaxation in the rotating frame (R1ρ) is a unique method for atomic‐resolution characterization of conformational (chemical) exchange processes occurring on the microsecond timescale. We present a rotating‐frame 13Cα relaxation dispersion experiment for measuring conformational dynamics in uniformly 13C‐labeled proteins. The experiment was validated by using the E140Q mutant of the C‐terminal fragment of calmodulin, which exhibits significant conformational exchange between two major conformations, as gauged from previous 15N and 1H relaxation studies. Consistent with previous work, the present 13Cα R1ρ experiment detects conformational‐exchange dynamics throughout the protein. The average correlation time of 〈τex〉=25±8 μs is in excellent agreement with those determined previously from 1H and 15N R1ρ relaxation data: 〈τex〉=19±7 and 21±3 μs, respectively. The extracted chemical‐shift differences between the exchanging states reveal significant fluctuations in dihedral angles within single regions of Ramachandran φ–ψ space, that were not identified from the 1H and 15N relaxation data. The present results underscore the advantage of using several types of nuclei to probe exchange dynamics in biomolecules.
Solid‐ and Solution‐State Studies of the Novel μ‐Dicyanamide‐Bridged Dinuclear Spin‐Crossover System {[(Fe(bztpen)]2[μ‐N(CN)2]}(PF6)3⋅n H2O

Published: July 2005

The mononuclear diamagnetic compound {Fe(bztpen)[N(CN)2]}(PF6)CH3OH (1) (bztpen = N‐benzyl‐N,N′,N′‐tris(2‐pyridylmethyl)ethylenediamine) has been synthesized and its crystal structure studied. Complex 1 can be considered to be the formal precursor of two new dinuclear, dicyanamide‐bridged iron(II) complexes with the generic formula {[(Fe(bztpen)]2[μ‐N(CN)2]}(PF6)3⋅n H2O (n = 1 (2) or 0 (3)), which have been characterized in the solid state and in solution. In all three complexes, the iron atoms have a distorted [FeN6] octahedral coordination defined by a bztpen ligand and a terminal (1) or a bridging dicyanamide ligand (2 and 3). In the solid state, 2 and 3 can be considered to be molecular isomers that differ by the relative position of the phenyl ring of the two {Fe(bztpen)[N(CN)2]}+ halves (cis and trans, respectively). Depending on the texture of the sample, 2 exhibits paramagnetic behavior or displays a very incomplete spin transition at atmospheric pressure. Complex 3 undergoes a gradual two‐step spin transition with no observed hysteresis in the solid state. Both steps are approximately 100 K wide, centered at ≈200 K and ≈350 K, with a plateau of approximately 80 K separating the transitions. The crystal structure of 3 has been determined in steps of approximately 50 K between 400 K and 90 K, which provides a fascinating insight into the structural behavior of the complex and the nature of the spin transition. Order–disorder transitions occur in the dicyanamide bridge and the PF6− ions simultaneously, with the spin‐crossover behavior suggesting that these transitions may trigger the two‐step character. In solution, 2 and 3 display very similar continuous spin conversions. Electrochemical studies of 2 and 3 show that the voltammograms are typical of dimeric systems with electronic coupling of the metals through the dicyanamide ligand.
Highly Efficient Redox Isomerization of Allylic Alcohols at Ambient Temperature Catalyzed by Novel Ruthenium–Cyclopentadienyl Complexes—New Insight into the Mechanism
Authors: Martín‐Matute Belén , Bogár Krisztián , Edin Michaela , Kaynak F. Betül , Bäckvall Jan‐E.
Published: July 2005

A range of ruthenium cyclopentadienyl (Cp) complexes have been prepared and used for isomerization of allylic alcohols to the corresponding saturated carbonyl compounds. Complexes bearing CO ligands show higher activity than those with PPh3 ligands. The isomerization rate is highly affected by the substituents on the Cp ring. Tetra(phenyl)methyl‐substituted catalysts rapidly isomerize allylic alcohols under very mild reaction conditions (ambient temperature) with short reaction times. Substituted allylic alcohols have been isomerized by employing Ru–Cp complexes. A study of the isomerization catalyzed by [Ru(Ph5Cp)(CO)2H] (14) indicates that the isomerization catalyzed by ruthenium hydrides partly follows a different mechanism than that of ruthenium halides activated by KOtBu. Furthermore, the lack of ketone exchange when the isomerization was performed in the presence of an unsaturated ketone (1 equiv), different from that obtained by dehydrogenation of the starting allylic alcohol, supports a mechanism in which the isomerization takes place within the coordination sphere of the ruthenium catalyst.
