The acceptorless dehydrogenative cross-coupling of primary alcohols to form cross-esters with the liberation of H2 gas was enabled using a [RuCl(η6-C6H6)(κ2-CNP)][PF6]Cl complex as the catalyst. This sustainable protocol is applicable to a broad range of primary alcohols, particularly for the sterically demanding ones, featuring good functional group tolerance and high selectivity. The good catalytic
使用 [RuCl(η 6 -C 6 H 6 )(κ 2 -CNP)][PF 6 ]Cl 络合物,可以实现伯醇的无受体脱氢交叉偶联以形成交叉酯并释放 H 2气体催化剂。这种可持续的协议适用于广泛的伯醇,特别是对于空间要求高的伯醇,具有良好的官能团耐受性和高选择性。良好的催化性能可归因于氮-膦功能化的N-杂环卡宾(CNP)配体,它采用面配位模式以及配位苯的容易解离。
