A photocatalytic hydroamidomethylation of azobenzenes with N,N-dimethylamides has been developed. Using tetrabutylammonium decatungstate (TBADT) as a photocatalyst, an array of azobenzenes and N,N-dimethylamides reacted smoothly under visible light irradiation, affording previously unreported N-amidomethyl-N,N′-diarylhydrazines in generally high yields. Mechanistic studies indicate that the reaction is enabled by TBADT-mediated hydrogen atom transfer (HAT) photocatalysis. This work is fundamentally different from the previously reported reaction of N,N-dimethylformamide with azobenzenes.

Decatungstate-光催化偶氮苯与 N,N-二甲基酰胺的氢酰胺甲基化



已经开发了偶氮苯与 N,N-二甲酰胺的光催化氢酰胺甲基化。使用十二酸四丁基铵 (TBADT) 作为光催化剂,一系列偶氮苯和 N,N-二甲酰胺在可见光照射下反应顺利,以普遍高产率得到以前未报道的 N-酰胺甲基-N,N′-二芳酰肼。机理研究表明,该反应是由 TBADT 介导的氢原子转移 (HAT) 光催化实现的。这项工作与以前报道的 N,N-二甲基甲酰胺与偶氮苯的反应有着根本的不同。
