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]

For cyclic systems: Identification of the parent cyclic ring. The cyclic system must obey these rules, in order of precedence: It should have the most senior heteroatom (in order: N, O, S, P, Si, B). It should have the maximum number of rings. It should have the maximum number of atoms. It should have the maximum number of heteroatoms.
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.

Like BPA, CBDO is a diol with a structure suitable for making polyesters. CBDO’s C 4 ring is sufficiently rigid to prevent the two OH groups from forming cyclic structures. Unlike BPA, there is no current evidence of carcinogenic or toxic effects from CBDO-based consumer products.
A boronic acid is an organic compound related to boric acid (B(OH) 3) in which one of the three hydroxyl groups (−OH) is replaced by an alkyl or aryl group (represented by R in the general formula R−B(OH) 2). [1] As a compound containing a carbon–boron bond, members of this class thus belong to the larger class of organoboranes.
