4-Bromophenol → 4-Bromo-2-(1,1-dimethyldecyl) phenol

Participants

Reaction Steps

A mixture of 2-methyl-1-undecene (35.6 g, 211 mmoles), parabromphenol (36.6 g, 211 mmoles) and Dowex 50×12 resin (100-200 mesh) previously washed with water, rinsed with acetone and oven dried for 3 hours at 80° C., is heated at 100°-110° C. for 48 hours. The mixture is then cooled to ambient temperature and chromatographed on a silica column (eluant: a mixture of dichloromethane, 40% and hexane, 60%), yielding 4-bromo-2-(1,1-dimethyldecyl)-phenol in the form of a pale yellow oil. (30.85 g, 43%).
