chloride as a catalyst and chlorotrimethylsilane as an additive. The highly electrophilic and oxophilic tungsten catalyst enables the selective scission of a C–N bond of tertiary alkyl amides to effect transamidation of a myriad of structurally and electronically diverse tertiary alkyl amides and amines. Mechanistic study implies that the synergistic effect of the catalyst and the additive could pronouncedly
转酰胺最近已成为使酰胺多样化的一种简单方便的方法。然而,臭名昭著的、完全烷基取代的叔酰胺的动力学和热力学要求的转酰胺化仍然是一个长期的挑战。在这里,我们描述了一种使用简单的氯化钨 (VI) 作为催化剂和三甲基氯硅烷作为添加剂来活化叔烷基酰胺以简化转酰胺化的方法。高度亲电和亲氧的钨催化剂能够选择性地切断叔烷基酰胺的 C-N 键,从而实现无数结构和电子不同的叔烷基酰胺和胺的转酰胺化。
