A common diol reaction to produce a cyclic ether. 1,2-diols and 1,3-diols can be protected using a protecting group. [13] Protecting groups are used so that the functional group does not react to future reactions. Benzylidene groups are used to protect 1,3-diols. [13]
Particularly common spiro compounds are ketal (acetal) formed by condensation of cyclic ketones and diols and dithiols. [15] [16] [17] A simple case is the acetal 1,4-dioxaspiro[4.5]decane from cyclohexanone and glycol. Cases of such ketals and dithioketals are common.

In cyclic systems, the reaction presents more features of interest. In these reactions, the stereochemistry of the diol plays a crucial role in deciding the major product. An alkyl group which is situated trans- to the leaving –OH group may migrate to the carbocation center, but cis- alkyl groups migrate at a very low rate.
The molecular formula C 6 H 12 O 2 (Molar mass: 116.15 g/mol) may refer to: ... Cyclohexane-1,2-diol, a chemical compound found in castoreum; Diacetone alcohol
Two ketyl groups react in a coupling reaction yielding a vicinal diol with both hydroxyl groups deprotonated. Addition of water or another proton donor gives the diol. With magnesium as an electron donor, the initial reaction product is a 5-membered cyclic compound with the two oxygen atoms coordinated to the oxidized Mg 2+ ion.
The reaction mechanism involves the formation of a cyclic thiocarbonate from the diol and thiophosgene.The second step involves treatment with trimethyl phosphite, which attacks the sulfur atom, producing S=P(OMe) 3 (driven by the formation of a strong P=S double bond) and leaving a carbene. [6]
Vinylene carbonate can also be thought of as the cyclic carbonate of the hypothetical (Z)-ethene-1,2-diol. The activated double bond in this five-membered oxygen-containing heterocycle makes the molecule a reactive monomer for homopolymerization and copolymerization and a dienophile in Diels-Alder reactions. Below room temperature vinylene ...
