1-(trifluoromethyl)alkenes through nickel-catalyzed alkylation/arylation of 1-chloro-3,3,3-trifluoroprop-1-ene (HCFO-1233zd) with alkyl/aryl zinc reagents and cobalt-catalyzed reductive cross-coupling between HCFO-1233zd and aryl bromides has been developed. These approaches feature broad substrate scope, high functional group tolerance, and the use of industrial feedstocks and low-cost nickel/cobalt catalysts
通过镍催化的 1-氯-3,3,3-三氟丙-1-烯 (HCFO-1233zd) 烷基化/芳基化与烷基/芳基锌试剂和钴催化的还原交叉合成 1-(三氟甲基) 烯烃HCFO-1233zd 和芳基溴化物之间的偶联已经开发出来。这些方法具有广泛的底物范围、高官能团耐受性以及使用工业原料和低成本镍/钴催化剂的特点,为获取 1-(三氟甲基) 烯烃提供了简便的途径。所得 1-(三氟甲基) 烯烃的多种转化证明了当前方法的合成效用。
