Abstract

This study describes the application of indolylphosphine ligands with a diphenylphosphino moiety to the palladium-catalyzed borylation of aryl chlorides. The combination of palladium metal precursor with PPh2-Andole-phos, which comprises an inexpensive− PPh2 group, provides highly effective catalysts for the borylation of aryl chlorides. A range of functional groups such as− CN,− NO2,− CHO,− COMe,− COOMe, and− CF3 was compatible, and ...
