Four organic-inorganic hybrid complexes ([(HL1)2SnCl 6]·2H2O (1) (L1=2-methylquinoline), [(HL2) 2(CdCl4)]·2H2O (2) (L2=5,7-dimethyl-1,8- naphthyridine-2-amine), [(H2L2)2SnCl6]2(Cl) (3), and [(H2L3)SnCl6]·2H2O (4) (L3=3,6-bis(imidazol-1-yl)pyridazine)) derived from N-containing aromatic Brnsted bases and metal(II) chloride dihydrate (tin(II) chloride dihydrate and cadmium(II) chloride dihydrate) were prepared and characterized by IR, X-ray structure analysis, elemental analysis, and TG analysis. The aromatic rings of the cations in all of the compounds are essentially planar. X-ray diffraction analysis revealed that 2-4 have 3-D network structures built from hydrogen bonds between the cations and chlorometallates. Water molecules also play important roles in structure extension in 1, 2, and 4. The arrangements of the anions and cations in their solid state are dominated by shape, size, and symmetry of the cations and the different structures of the chlorometallates as well as by hydrogen-bond interactions.

In order to deprotect N-carbobenzoxy-l-aminoacids (Cbz-AA) and related compounds, a series of microorganisms was selected from soil by enrichment cultures with Cbz-l-Glu as sole nitrogen source. A lyophilized whole-cell preparation of two Arthrobacter sp. strains grown on Cbz-Glu or Cbz-Gly exhibited a high cleavage activity. The conditions of hydrolysis have been optimized and a quantitative enantioselective deprotection of several Cbz-dl-amino acids was obtained, as well as the deprotection of N-carbamoylester derivatives of several synthetic amino compounds. The preparation of Cbz-d-allylglycine and l-allylglycine in high yield and high optical purity is described as an application of this method.

A first principle study of the cross-coupling reaction between 3-chloro-6-iodopyridazine and triphenylbismuth under palladium catalysis has been carried out. The approach selected for this investigation is the density functional theory within the framework of the PBE0 and B3LYP hybrid exchange?correlation functionals, with and without including empirical corrections for the dispersion forces at the GD3 level. For this reaction, a three-step mechanism including an oxidative addition, a transmetalation and a reductive elimination has been proposed. All intermediates and transition states have been fully characterized. The energy profile is deduced in gas phase and in solvent. Calculations suggest that the oxidative addition is the rate-determining step for the entire cross-coupling reaction.
