Abstract

Abstract Moisture/air-stable and robust phosphine mono-and bis-ylide palladacycles as catalyst precursors were used in Suzuki and Heck cross-coupling reactions with different aryl halides including electron-rich and electron-deficient substituents. These coupling reactions could proceed smoothly in air under optimized reaction conditions (Suzuki coupling: 0.001 mol% of palladacycle, Cs 2 CO 3 in DMF at 110 C; Heck coupling: 0.001 ...
