The preparation of 1,2-ethanediol was described in part ( b ). One method of preparing formaldehyde is by ozonolysis of ethylene. Another method is periodate cleavage of 1,2-ethanediol. Cyclic acetal formation is then carried out in the usual way. ( d ) Acetylenic alcohols are best prepared from carbonyl compounds and acetylide anions. Acetaldehyde is available as in part ( a ).
