Fluorescent diarylindoles by palladium-catalyzed direct and decarboxylative arylations of carboxyindoles.

Abstract

Simple and brilliant: 1-Substituted 1H-indole-2-carboxylic acids efficiently undergo successive diarylation accompanied by C-H bond cleavage and decarboxylation upon treatment with aryl bromides in the presence of a palladium catalyst system to afford fluorescent 2,3-diarylindoles. This facile synthetic method provides a highly efficient blue emitter with a… (More)
