Palladium-catalyzed Suzuki couplings using a novel diaminophosphine oxide as ligand

A novel diaminophosphine oxide was synthesized and applied as ligand in palladium-catalyzed Suzuki couplings reaction of aryl bromides and chlorides. The coupling reaction proceeded smoothly at mild conditions using 2 mol% Pd2(dba)3 in the presence of tBuOK.
