Ph3SiCl, which suggests that the silyl chloridesactivate CO2 in cooperation with AlBr3. 1H NMR analysis of unworked-up reaction mixtures reveals that the products merge as aluminum carboxylates. The mass balance concerning silicon indicates that the silyl chlorides are recycled during the reaction sequence. On the basis of these observations, a feasible mechanism is proposed for the present carboxylation

Reactions of M(OAc)2·nH2O and M(OAc)2(tmeda) with dithiocarboxylic acids gave [M(S2CTol)2]n (1) (M = Zn or Cd; Tol = C6H4Me-4) and [M(S2CAr)2(tmeda)] (3) (M = Zn, Cd, Hg; Ar = Ph or Tol), respectively, in high yields as deep-colored crystalline solids. The former are soluble in pyridine to give pyridine adducts [M(S2CTol)2(py)] (2). These complexes were characterized by elemental analysis, UV/Vis and

characterized by elemental analyses and spectroscopic methods. Molecular structures of [RBi(S2Ctol)2] (R = Me or Ph) have been established by single crystal X-ray diffraction studies. The bismuth atom in these complexes adopts a square pyramidal configuration with the R group at the apical position. In the solid state, these complexes show supra-molecular association devoid of Bi⋯S secondary interactions. Thermolysis
