The synthetic utility of fluorinated vinylstannanes has been explored. This methodology provides a convenient and simple synthesis of trifluoromethylated vinyl sulfides in 60-97% yields with the formation of the E-isomer exclusively. The reaction is stereospecific and of wide scope including various types of thiols (aryl, benzyl, alkyl thiols, and thiols with an ethoxycarbonyl moiety) used as substrates. A possible mechanism is proposed.
已探讨氟化乙烯基锡化合物的合成实用性。这一方法提供了一种便捷简单的合成三氟甲基乙烯基硫化物的方法,产率为60%-97%,且仅形成E-异构体。该反应具有立体选择性,适用范围广泛,包括多种类型的硫醇(芳香族、苄基、烷基硫醇,以及含乙氧基羧基的硫醇)作为底物。提出了一种可能的机制。
