A 100 mL of reactor equipped with magnetic stir bar was charged with 140 mg (0.15 mmol) of {[(t-Bu)2P(OH)]2PdCl}2, 1.27 g (10.0 mmol) of 4-chlorotoluene, and 10.0 mmol of KPPh2 in 30.0 mL of THF. The resulting mixture was refluxed for 17 h before the reaction was cooled to room temperature, quenched with with 20 mL of H2O. The phosphorus-31 NMR spectrum of the reaction mixture at this point showed the δ32.1 [˜10%, Ph2PH(O)] and −5.0 (˜90%, MeC6H4-PPh2) resonances.
