Preparation of Primary Alkylantimony Compounds

Abstract

Abstract In comparison with the lighter group-V elements, access to primary alkyl compounds of antimony [containing either RSb(III) or RSb(V)] is impeded by the low thermal stability of the hydrides, RSbH2, and the puzzling non-existence of alkylstibonic acids, RSbO(OH)2. Existing procedures for the preparation of RSbX2 (X = halogen) frequently yield products which are difficult to separate and often have limited general application. New synthesis procedures and improvements in earlier procedures are described
