Sequential addition reactions of two molecules of Grignard reagents to thioformamides were found to yield tertiary amines in an efficient manner. The addition of two different Grignard reagents can be accomplished by using one equivalent of arylmagnesium reagent in the first step. In the second step, a variety of reagents such as alkyl, alkenyl, aryl, and alkynyl reagents were used to afford the corresponding
发现两个分子的格氏试剂与硫代甲酰胺的顺序加成反应可以有效地产生叔胺。可以通过在第一步中使用一当量的芳基镁试剂来完成两种不同的格氏试剂的添加。在第二步中,使用各种试剂(例如烷基,烯基,芳基和炔基试剂)以高收率或高收率得到相应的胺。
