A diol is a chemical compound containing two hydroxyl groups (−OH groups). An aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol. Examples of diols in which the hydroxyl functional groups are more widely separated include 1,4-butaned… WitrynaA glycol, also known as a vicinal diol, is a compound with two -OH groups on adjacent carbons. Introduction The reaction with O s O 4 is a concerted process that has a cyclic intermediate and no rearrangements. Vicinal syn dihydroxylation complements the epoxide-hydrolysis sequence which constitutes an anti dihydroxylation of an alkene.
