cobalt-catalyzed tail-to-tail hydrodimerization of activated alkenes to 1,4-difunctional butanes, providing a general route to important industrial intermediates to nylon 6,6. This protocol is highly efficient for various activated alkenes at ambient temperature utilizing hantzsch ester as a recyclable two-electron and two-proton donor with assistant of catalytic amount of base as the proton shuttle
这项工作揭示了一种可见光诱导的钴催化尾对尾加氢二聚活性烯烃到 1,4-双官能丁烷,为尼龙 6,6 的重要工业中间体提供了一般途径。该协议对环境温度下的各种活化烯烃非常有效,利用 hantzsch 酯作为可回收的双电子和双质子供体,辅以催化量的碱作为质子穿梭。
