A mixture of 3-methyl-3-hydroxybut-1-ene (32 g.), acetic acid (150 ml.) and boric acid (30 g.) was stirred at 105° for 4 hours. The cooled reaction mixture was diluted with water, neutralised with solid sodium carbonate and extracted with ether (3 × 50 ml.) The combined ethereal extracts were brine washed, dried and the solvent removed giving a pale yellow oil (30 g.) Distillation gave 3,3-dimethylallyl acetate as a colourless oil (22 g.) b.p. 44°-45°/14 mm Hg.
