摘要

Abstract: The bicyclic hydridophosphorane 2 (Z4PH) was shown to undergo UV-light- induced alkylthiylation reactions with a series of alkyl disulfides (RSSR, R= CH3, n-Bu, neopentyl, sec-Bu, and t-Bu) to give the corresponding isolable thiaphosphoranes (Z4PSR) in preparatively useful amounts (61-loo%), except for t-BuSSBu-t which gave a poor yield of product. The reactions of the alkyl disulfides were all inhibited by a-methylstyrene. ...
