A solution of the catalyst was prepared as follows: An oven-dried Wheaton vial equipped with a magnetic stir bar was charged with Pd(OAc)2 (5.60 mg, 0.025 mmol, 1.0 eq.) and 2-dicyclohexylphosphino-2′,4′,6′-tri-iso-propyl-1,1′-biphenyl (4c) (24.5 mg, 0.050 mmol, 2.0 eq.). Toluene (3.0 mL) was added and the vial was sealed with a PTFE-lined plastic cap. The resulting mixture was stirred at 23° C. for 1 h to yield a reddish Pd/4c catalyst solution (0.00833 N Pd in toluene).
