Reaction Steps

The general procedure A was followed using 1,2-dibromobenzene (58.6 uL, 0.5 mmol) and B2pin2 (126.9 mg, 0.5 mmol, 1.0 eq.) as starting material. The resulting mixture was allowed to stir 16 hours at 80 oC. 5j was obtained as colorless oil (178.2 mg, 98%) after purification by silica gel flash chromatography (EtOAc/PE=1:50 v/v).
