Zr-catalyzed carbomagnesations are disclosed, where in contrast to previous catalytic carbomagnesations the alkyl moiety of the electrophile is transferred (vs that of the Grignard reagent). The identity of the Grignard reagent is manipulated so that Zr-Mg exchange is facilitated, leading to the formation of alkylmagnesium halide products.
[反应:参见结构]公开了有效的亲电Zr催化碳还原反应的第一个实例,其中与先前的催化碳还原反应相反,亲电子的烷基部分被转移(相对于格利雅试剂的烷基部分)。
格氏试剂的身份得到控制,以便促进Zr-Mg交换,从而导致烷基
镁卤化物产物的形成。
