We have recently developed palladium-catalyzed methods for direct arylation of indoles (and other azoles) wherein high C-2 selectivity was observed for both free (NH)-indole and (NR)-indole. To provide a rationale for the observed selectivity ("nonelectrophilic" regioselectivity), mechanistic studies were conducted

This communication describes the rational development of a PdII-catalyzed method for the direct 2-arylation of indoles using [Ar-IIII-Ar]BF4. These reactions proceed under remarkably mild conditions (often at room temperature and in the presence of ambient air and moisture), and these

A novel and efficient method for the Au(III)/TPPMS-catalyzed direct substitution reaction of benzhydryl and benzylic alcohols with indoles in water is developed. Au(III)/TPPMS is an effective catalyst for the benzylation of the strong π nucleophile 1-methylindole, while common Brønsted or
