A palladium-catalyzed oxidative C–H bond decarboxylative acylation of N-nitrosoanilines using α-oxocarboxylic acid as the acyl source is described. The catalyst Pd(OAc)2 and oxidant (NH4)2S2O8 enabled ortho-acylation of N-nitrosoanilines at room temperature, affording an array of N-nitroso-2-aminobenzophenones in moderate to excellent yields.
描述了使用α-氧代羧酸作为酰基源的钯催化的N-亚硝基苯胺的氧化C–H键脱羧酰化反应。催化剂Pd(OAc)2和氧化剂(NH 4)2 S 2 O 8可以在室温下对N-亚硝基苯胺进行邻酰化,从而以中等至极好的收率提供了一系列N-亚硝基-2-氨基二苯甲酮。
