Abstract

A novel decarboxylative N-arylation of indole-2-carboxylic acids with aryl halides is developed. The reaction proceeds efficiently in the presence of Cu2O as the catalyst to give the corresponding N-aryl indoles in high yields. This synthetic method shows good functional group tolerance and offers an alternative route to construct N-aryl indoles.
