method for a carbon-silicon or carbon-carbon bond forming reaction between allyl ethers and chlorosilanes, alkyl tosylates, or alkyl halides giving rise to allylsilanes or alkenes has been developed. This reaction proceeds efficiently at ambient temperature by the combined use of nickel catalysts and a vinyl-Grignard reagent. A possible reaction pathway involving the formation of allyl-Grignard reagents
已经开发出一种新的方法,用于在烯丙基醚和氯硅烷,烷基甲苯磺酸盐或烷基卤化物之间形成烯丙基硅烷或烯烃的碳-硅或碳-碳键形成反应。通过结合使用镍催化剂和乙烯基格氏试剂,该反应在环境温度下有效地进行。提出了一种可能的反应途径,该反应途径包括通过π-烯丙基镍配合物与乙烯基-格氏试剂的金属转移,以及随后用亲电子试剂捕获如此形成的烯丙基-格氏试剂来形成烯丙基-格利雅试剂。
