The first examples of facile hydrothiophosphorylation of organyl vinyl sulfoxides are described. Nucleophilic addition of P,S-ambident secondary phosphine sulfides 1 and 2 to organyl vinyl sulfoxides 3-6 with potassium hydroxide at room temperature proceeds chemo- and regioselectively to give the corresponding bis(2-organylethyl)[2-(organylsulfinyl)ethyl]phosphine sulfides 7a-e in high isolated yields.
本研究首次介绍了羰基
乙烯基硫醚的简便氢
硫磷化实例。在室温下,用
氢氧化钾将 P、S-反式仲膦
硫化物 1 和 2 与羰基
乙烯基硫醚 3-6 进行亲核加成,以
化学和区域选择性的方式得到相应的双(2-羰基乙基)[2-(羰基亚磺酰基)乙基]膦
硫化物 7a-e,分离产率很高。
