Vorschrift

2,2-Dimethyl-3-octenoic acid is prepared by adding 2,2-dimethyl-3-octene nitrile (1.51 g, 0.01 m) to a solution prepared from 15% NaOH in butanol/H2O (2:3) (30 mL). The reaction mixture is stirred and refluxed for 7 hours, is cooled and made acidic with 10% hydrochloric acid. The reaction mixture is extracted with diethyl ether and the extract washed with saturated NaCl and dried over MgSO4, filtered and concentrated to give 2,2-dimethyl-3-octenoic acid.
