The solvolysis of 2-chloro-2, 3, 3-trimethylpentane in 80% aqueous ethanol forms pure 2, 3, 3-trimethyl-l-pentene in 58% yield. The mixture of alcohol and ethyl ether in the solvolysis is converted by hydrogen chloride into a tertiary chloride with identical properties with the original material. In 80% acetone the solvolysis proceeds to give the pure olefin (50% yield) and pure 2, 3, 3-trimethyl-2-pentanol (20% yield). The solvolysis of 3-chloro-2, 2, 3- ...
