反応手順
It has been disclosed in Bull. Soc. Chim. France 11 (1944), 218-223, that a mixture of aldehydes is obtained when an unsaturated diol is reacted with dilute sulfuric acid or equimolar amounts of phosphoric acid and water. Thus, a mixture of pent-2-enal and pent-3-enal is obtained from pent-2-ene-1,4-diol, a mixture of hex-2-enal and hex-3-enal is obtained from hex-2-ene-1,4-diol, and a mixture of 2,3-dimethylbut-2-enal and 2,3-dimethylbut-3-enal is obtained from 2,3-dimethylbut-2-ene-1,4-diol.
