  Silver(I) catalyzed oxidation of thiocarboxylic acids into the corresponding disulfides and synthesis of some new Ag(I) complexes of thiophene-2-thiocarboxylate

  摘要：

  Aromatic thiocarboxylic acids in presence of a base on treatment with silver nitrate under ambient conditions were oxidized to the corresponding disulfides. The reactions were found to be catalyzed by Ag+ ions. The catalytic oxidation is paralleled by the Ag(SCOAr) complex formation reaction which could be considerably subsided by adjustment of the reaction conditions. Attempts to use (Ag(PPh3)(2)](+) or [Ag(PPh3)](+)r ion as the catalyst were unsuccessful as these resulted in the formation of the corresponding thiocarboxylate complexes. The products, ArCOSSCOAr (1, 2), [Ag(SCOAr)(PPh3)(2)] (3, 4) and [Ag(SCOAr)(PFh(3))](4) (5) (Ar = C6H5, C4H3S) were characterized by single crystal X-ray analysis. Compounds 3 and 4 are monomeric while 5 is a cyclic tetramer in the crystalline phase. (C) 2010 Elsevier Ltd. All rights reserved.

  having three fused four-membered rings. The formation of conformational isomers 3 and 4 may be attributed to packing effects. The ability of the sulfur atom in PhCO}S− ligand forming μ-S and μ3-S bridging, and that of AgI to display variable coordination geometries have aided the formation of two deformational isomers 5 and 6. The variable temperature 31P NMR of compound 1 may be interpreted in terms of
