Boron trifluoride etherate → 2-Propylpentanal

To a vigorously stirred solution of 2 propyl 1,2 epoxypentane (1 equivalent), prepared as described in Example 1, in benzene cooled to 0° was added a solution of boron trifluoride etherate (0.5 equivalents) in benzene. The reaction mixture was stirred for 1 min and was quenched by the addition of water. Following separation of the phases, the organic phase was washed with saturated aqueous sodium bicarbonate and water, dried with magnesium sulfate, filtered and concentrated to give a colorless oil. The oil was distilled to give the desired product as a colorless oil; 75% yield; boiling point (b.p) 60-63° /0.1 mm.
