Organosilicon compounds have been extensively utilized both in industry and academia. Studies on the syntheses of diverse organosilanes is highly appealing. Through‐space metal/hydrogen shifts allow functionalization of C−H bonds at a remote site, which are otherwise difficult to achieve. However, until now, an aryl to alkyl 1,5‐palladium migration process seems to have not been presented. Reported
有机硅化合物已广泛用于工业和学术界。关于多种有机硅烷的合成的研究非常吸引人。穿越空间的金属/氢转移可在远程位置实现CH键的功能化,否则很难实现。但是,到目前为止,似乎还没有出现过芳基到烷基1,5-钯的迁移过程。本文报道的是硅上甲基的远程烯烃化,芳基化和硼化,以访问各种乙烯基硅烷,苄基硅烷和硼烷基硅烷,构成基于1,5-钯迁移过程的独特C(sp 3)-H转化。
