Abstract

A simple catalytic system based on PdCl2 and triphenylphosphine chalcogenides (PPh3X; X= O, S, Se) is found to be highly effective (up to 97% isolated yield) in the room temperature Suzuki–Miyaura reactions. Under the same experimental conditions, triphenylphosphine chalcogenides as ligands show superior activities compared to free triphenylphosphine.
