PhSbCl2. Oxidation of the antimony(III) compounds 1, 3 and 5 with one equivalent of SO2Cl2 proceeded smoothly with formation of organoantimony(V) compounds LSbCl4 (7), LSb(Ph)Cl3 (8) and LSbPh2Cl2 (9) in nearly quantitative yields. Compounds 7–9 are yellowish solids that are stable for a long time even in the presence of air. In contrast, only organobismuth(III) compounds 4 and 6 could be successfully oxidized
