Synthesis and structural characterization of diorganotin(IV) esters of salicylidene-amino acids
摘要:
Eight diorganotin esters of salicylidene-L-tryptophan(Sal-T) and salicylidene-L-valine(Sal-V), [(n-Bu)(2)Sn(Sal-T)] (1), [(n-Bu)(2)Sn(Sal-V)] (2), [Ph2Sn(Sal-T)] (3), [Ph2Sn(Sal-V)] (4), [(PhCH2)(2)Sn(Sal-T)] (5), [(PhCH2)(2)Sn(Sal-V)] (6), [(4-ClC6H4CH2)(2)Sn(Sal-T)] (7) and [(4-ClC6H4CH2)(2)Sn(Sal-V)] (8) have been synthesized and characterized by elemental analysis, IR and H-1 NMR. The crystal structures of compounds 1 and 2 have been determined by X-ray single crystal diffraction. Their structures show the tin atoms of two compounds are rendered five-coordinated in distorted trigonal bipyramidal geometries. (C) 2004 Published by Elsevier B.V.
Catalytic oxidation of diorganotin(IV) carboxylates to mixed-ligand monoalkyltin(IV) carboxylates by Ag+ and structure characterization of the mixed-ligand monoalkyltin(IV) 2-pyridinecarboxylate (2-ClPhCH2)Sn(2-ClPhCO2)(O2CC5H4N-2)2

The complexes of the type (ArCH2)(2)SnO were catalytic-oxygenated by Ag+ and yielded mixed-ligand organotin(IV) complexes (ArCH2)(2-C5H4NCO2)(2)(ArCOO)tin(IV) (Ar = C6H5 (1), 2-ClC6H4 (2), 2-CNC6H4 (3), 4-ClC6H4 (4), 4-CNC6H4 (5), 2-FC6H4 (6)). The complexes 1-6 are characterized by elemental analyses, IR and NMR (H-1, C-13, Sn-119) spectroscopies. Single X-ray crystal structure analysis has been determined, which reveals that the center tin atom of complex 2 is seven-coordinated geometry. (c) 2006 Elsevier B.V. All rights reserved.
