Participants

Reaction Steps

Bromine (a 2M solution in dichloromethane; 955 mg, 5.97 mmol) was added to a solution of 1,2-bis (diphenyl)phosphinoethane (1.16 g, 2.99 mmol) in dichloromethane (15 ml) at 0°. A solution of 5-(2-napthyl)pentan-1-ol (513 mg, 2.39 mmol) in dichloromethane (5 ml) was added to the 0° solution. The solution was warmed to room temperature and stirred for 1.5 hours. The solution was diluted with ethyl ether/pentane (1:3), filtered through a thin pad of celite and the solvent evaporated. The resulting oil was purified by flash chromatography (hexane) giving the title compound as a colorless oil.
