This report presents the first example of nickel‐catalyzed mild decarboxylative cross‐coupling reaction for the regioselective formation of C–Si bond. An easily accessible and significantly stable Ni (dmg)2 owes the role of key promoter. This reaction is highly functional group tolerant and offers α,β‐unsaturated silanes in synthetically useful yields. The reaction gives access to the successful utilization
本报告提出了镍催化的C-Si键区域选择性形成的轻度脱羧交叉偶联反应的第一个例子。Ni(dmg)2易于获得且非常稳定,这归因于关键启动子的作用。该反应具有高度的官能团耐受性,可提供合成有用的α,β-不饱和硅烷。该反应使人们可以成功利用原本困难的三烷基硅烷作为偶联伙伴,并在适中的温度下操作,这对于处理高挥发性硅烷是有利的。
