reductant is introduced. The reaction proceeds via the hydrogen splitting by B(2,6-F2-C6H3)3 in combination with chloride as the Lewis base. Density functional theory calculations support the unprecedented role of halides as active Lewis base components in the frustrated Lewis pair mediated hydrogen activation. The reaction displays broad substrate scope for tertiary benzoic acid amides and α-branched carboxamides
介绍了一种以草酰氯为活化剂、氢气为最终还原剂的羧酸酰胺无金属还原方法。该反应通过 B(2,6-F2-C6H3)3 与作为路易斯碱的氯化物组合进行氢分解而进行。密度泛函理论计算支持卤化物作为活性路易斯碱组分在受挫的路易斯对介导的氢活化中的前所未有的作用。该反应对叔苯甲酸酰胺和 α-支链甲酰胺显示出广泛的底物范围。
