Potassium tert-butoxide → 1-Bromo-4-(1-fluorovinyl)benzene

Participants

Reaction Conditions

Reaction Steps

796 mg (7.09 mmol) of potassium tert-butoxide were added in several portions to a solution, cooled to 0° C., of 1.0 g (3.55 mmol) of 1-bromo-4-(2-bromo-1-fluoroethyl)benzene in 10 ml of pentane. The resulting suspension was stirred at 0° C. for 30 min and then at RT for 1 h. The solid was filtered off, and the filtrate was washed with saturated ammonium chloride solution, dried over magnesium sulphate and carefully concentrated under reduced pressure. This gave 0.61 g (85.6% of theory) of the title compound.
