Abstract

Diaryl-, divinyl-, and dialkylindium compounds undergo a palladium-catalyzed cross-coupling reaction with aryl halides in aqueous THF to provide the corresponding coupling product in excellent yield. A wide range of functional groups are tolerated. The indium compounds can be generated from indium trichloride and two equimolar amounts of a Grignard reagent.
