Water → 1,2-Benzenediethanol

Participants

Reaction Steps

To a solution of 2,2′-(1,2-phenylene)diacetic acid (10 g, 51.5 mmol) in THF (100 mL) was added to LAH in THF (90 mL) dropwise, the mixture was refluxed for 18 hours. The mixture was cooled in ice bath and carefully added water (8 mL) dropwise, followed by 1 N NaOH (8 mL), then removed the ice bath added water slowly with stirring until the gray precipitate turns white. The mixture was filtrated and the filtrate was concentrated to give crude 2,2′-(1,2-phenylene)diethanol (8 g, 94%). 1H-NMR (CDCl3): 2.02 (s, 3H), 2.97 (m, 4H), 3.83 (m, 2H), 4.12 (m, 1H), 4.24 (t, 1H), 7.19 (m, 4H).
