Palladium-catalyzed P(O)R2 directed C–H arylation to synthesize electron-rich polyaromatic monophosphorus ligands†
Abstract
Palladium-catalyzed arylation of (diisopropylphosphoryl)biphenyl skeleton derivatives by the P(O)R2 directed C–H functionalization was reported. The related products were obtained in high regioselectivity and good functional group tolerance was observed. This reaction provided a new and efficient pathway for the synthesis of polyaromatic monophosphorus ligands.
