and efficientdirectC2‐arylation of free (NH)‐indoles with arylsulfinic acids proceeded through a microwave‐accelerated palladium‐catalyzed desulfitation reaction. By using PdCl2 as a catalyst, silver acetate as an oxidant, and H2SO4 as an additive, arylsulfinic acids with both electron‐donating and electron‐withdrawing groups underwent desulfitative coupling with an array of free (NH)‐indoles, thereby
游离(NH)吲哚与芳基亚磺酸的快速有效的直接C2-芳基化反应是通过微波促进的钯催化的脱硫反应进行的。通过使用PdCl 2作为催化剂,乙酸银作为氧化剂,H 2 SO 4作为添加剂,具有给电子基团和吸电子基团的芳基亚磺酸与一系列游离的(NH)吲哚进行脱硫偶联,从而有选择地提供高收率的C2-芳基吲哚。

A series of N-propargylanilines (0.2 mmol) and sulfinic acids (0.5 mmol) afforded 3-arylsulfonylquinoline derivatives in high yields (70–93%) and low current efficiencies upon electrooxidation. Electrolyses were carried out in a one-compartment cell, under constant current and ambient conditions, in methanol-nBu4NBF4 containing pyridine (0.4 mmol), without any added chemical oxidant.
