In the glovebox, a 25 mL pressure flask was charged with Pd2dba3 (228.9 mg, 0.25 mmol, 1.0 Pd eq.), P i Pr3 (229 L, 1.2 mmol, 2.4 eq.), 2,6-dimethyliodobenzene (87 L, 0.6 mmol, 1.2 eq.), and stirbar and dry benzene (5 mL). The vial was capped, removed from the glovebox and the purple solution was stirred at room temperature for 16 h, yielding a red solution. The mixture was filtered to removed palladium black and evaporated to dryness. The crude was the purified by sequential recrystallization from DCM/acetone in a freezer to remove dimers, and yielded 14e as pale yellow crystals (98.2 mg, 0.149 mmol, 29.8 %).
