Carbon tetrabromide → 1-(2-Bromoethyl)-2-cyclopropylbenzene

Participants

Reaction Steps

To a solution of 1-phenyl-1-cyclopropane methanol (1 g, 6.8 mmol) in 35 mL of THF is added triphenylphosphine (1.7 g, 7.1 mmol) and carbon tetrabromide (2.34 g, 7.1 mmol). The solution is stirred at ambient temperatures for 5 hours. After this time, the solution is diluted with 100 mL of Et2O. The reaction mixture is filtered and the collected solution is concentrated. The crude product is purified by column chromatography eluting with hexane to afford the title compound (1 g, 4.4 mmol) as an oil.
