Imidazolium salts from amino acids-a new route to chiral zwitterionic carbene precursors?
Kuehl, Olaf,Palm, Gottfried
, p. 393 - 397 (2010)
Chiral, carboxylic acid-functionalised imidazolium zwitterions were synthesised from the corresponding l-amino acids phenyl alanine, alanine and glycine (achiral). They form infinite C11 (10) chain structures in the solid state. The incorporation of water is dependent upon the creation of suitable cavities by the steric demands of the amino acid side chains.
Magnetostructural J-correlations in complexes with tetrahedro-{Cu 4} core

A comprehensive analysis of structural and magnetic data for 41 tetrahedro-{Cu4} complexes reveals that the exchange coupling constants (J2 and J4) correlate with averaged structural parameters of which the most informative are the averaged Cu-O-Cu angles in the bases (β) and walls (α) of the cubane structure. Using contemporary statistical programs, the cluster analysis, the principal component analysis, and the factor analysis bring information about the possible correlations of the magnetic and structural parameters and grouping of the parameters according to their similarity.

A series of [Au(NHC)2] (1a–4a) complexes supported by NHC ligands derived from glycine, alanine, methionine and phenylalanine (1–4 respectively) were prepared via a direct transmetalation reaction of their respective silver complexes. The Au complexes were characterized by ESI-MS and NMR spectroscopy in solution. These compounds exhibit instability when the solvent is removed; they displayed a strong tendency to form colored solutions in the order 4a > 3a?> 2a > 1a, which is associated with gold nanoparticles. 1a and 2a undergo oxidative addition of elemental bromine, yielding [Au(NHC)2Br2] (1b) for 1a and a mixture of [Au(NHC)2Br2] (2b) and [Au(NHC)Br3] (2c) for 2a. 2b and 2c were characterized by single crystal X-ray diffraction.
