The chemical and physical properties of amides change substantially when the electron-withdrawing groups attached to the nitrogen are varied. Herein, we report the superior performance of N-diphenylphosphinyl 1,2,3-triazolium amidate as a photoinduced hydrogen-atom transfer catalyst compared to its N-benzoyl analog. A binary catalyst system of the phosphinyl amidate and an Ir-based photocatalyst enables the alkylation of unbiased C–H bonds.

两性离子二苯基膦酰基酰胺酸酯作为一种强大的光诱导氢原子转移催化剂用于简单烷烃的 C-H 烷基化

当与氮相连的吸电子基团发生变化时，酰胺的化学和物理性质会发生显着变化。在此，我们报告了与其N-苯甲酰基类似物相比，N-二苯基膦酰基 1,2,3-三唑鎓酰胺酸盐作为光诱导氢原子转移催化剂的优越性能。膦酰基酰胺和 Ir 基光催化剂的二元催化剂体系能够实现无偏 C-H 键的烷基化。
