报道了在不加碱的条件下, 无配体铜盐能有效催化羧酸和氨基甲酰氯脱羧交叉偶联反应, 以CuCl2为催化剂、苯为溶剂, 于120 ℃条件下反应48 h即可实现脱羧交叉偶联过程. 在此标准条件下, 该催化体系对官能团普适性较好, 以较高收率获得了各种酰胺, 产物经1H NMR、13C NMR和HRMS表征

A ligand-free copper-catalyzed decarboxylative cross-coupling reaction of carboxylic acids and carbamoyl chlorides in the absence of base was developed. With CuCl2 as the catalyst, the decarboxylative cross-coupling process could be realized in benzene at 120 ℃ in 48 h. Under the standard condition, the catalytic system had good functional group tolerance, and diverse amides were obtained in good to high yields. The structures of products were elucidated by 1H NMR, 13C NMR and HRMS spectra.

Key words: copper-catalysis, decarboxylative cross-coupling, C—C bond formation, arylcarbamoyl chloride, amide
