Phosphinylthiolation of terminal alkynes with Ph2P(O)SBu or a related compound proceeds in the presence of a palladium–PEt3 catalyst system. Activity and stereoselectivity are highly dependent on the nature of solvent, ethylbenzene, and n-hexanol (or t-amyl alcohol) being E- and Z-selective, respectively.
在钯-PEt 3催化剂体系存在下,用Ph 2 P(O)SBu或相关化合物进行末端炔烃的膦酰基硫醇化反应。活性和立体选择性高度依赖于分别为E-和Z-选择性的溶剂,乙苯和正己醇(或叔戊醇)的性质。
