Abstract

Abstract Two new heterocyclic thiophosphoryl chlorides (2). derivatives of 1, 3, 2- benzodiazaphosphole, are synthesized. The reaction of respective thiophosphoryl chlorides (1) and (2) with AICI3 affords dimeric heterocyclic diphosphonium dications 3 and 4. The reaction of 2a with CF3SO3Ag gives rise to dimeric anhydride 5 instead of the expected δ5δ3-thiophosphoryl cations. The results show that δ5δ3-thiophosphonium cations ...
