Steps:

4.15. General procedure for H-MCR of aryl bromides with styrene

General procedure: To a 25mL RB flask was taken styrene (145.8 mg, 1.4 mmol), arylbromide (1.0 mmol), sodium acetate (90.2 mg, 1.1 mmol), TBAB(2.0 gm, 6.2 mol) and the catalyst (0.8 mg, 0.001 mmol). The reactionmixture was heated to 120 °C and stirred at the same temperaturefor 12 h and cooled. The organic portion from the reactionmixture was extracted with diethyl ether (2 15 mL). The extractswere combined and the volatiles removed on a rotavapor. Thedesired coupling product was isolated on a silica gel column usingn-hexane/ethyl acetate/n-hexane (2/98, v/v) mixture as eluent.
