Participants

Reaction Steps

Charge a Schlenck flask with palladium dibenzylidene acetone (88 mg, 0.16 mmol) and tri-o-furyl phosphine (72 mg, 0.31 mmol), purge with nitrogen and add 2 ml of dry THF. Stir for 2 minutes, until the deep purple solution turns to greenish yellow and add 1-iodo-2-bromo benzene (0.8 ml. 6.2 mmol) followed by 3-methyl-butyl zinc (0.5 M solution in THF, 30 ml, 15 mmol). React at rt for 4 hours. Add silica gel, concentrate, load onto a flash chromatography column and elute with hexane to obtain the title compound as a colorless liquid (1.1 g, 75%).
