Carbon centered radicals obtained by decarboxylative transformation of suitable thiohydroxamate esters react with group Va trisphenyl-sulphides to give intermediates of general formula R-M(SPh)2 (M = As, Sb, Bi). These react spontaneously with air to give the corresponding alcohols. This procedure is especially useful in the case where M=Sb. It is thus sufficient to stir the thiohydroxamate ester with
