A peroxy acid is an acid which contains an acidic –OOH group.

The vinyl ethers are susceptible to polymerization to give polyvinyl ethers. These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the carboxylate group carries myriad functionality. The process affords ethers. Phosphonyl radical addition to enol ethers. It is miscible with water as well as organic solvents. Nickel‐catalyzed C−H bond Alkoxylation of Amides with Alcohols. Ryohei Doi. [5], Alternatively, vinyl ethers can be prepared from alcohols by Iridium-catalyzed transesterification of vinyl esters, especially the widely available vinyl acetate: [6], Vinyl ethers can be prepared by reaction of ethyne and alcohols in presence of a base. Similarly, they undergo inverse demand Diels-Alder reactions. This colorless liquid has a pleasant ether-like odor.

Technical support issues arising from supporting information (other than missing files) should be addressed to the authors. Hydroperoxides or peroxols are compounds containing the hydroperoxide functional group (ROOH). In general, low molecular weight epoxides are colourless and nonpolar, and often volatile.

Acrylates (IUPAC: prop-2-enoates) are the salts and esters, and conjugate bases of acrylic acid. Similarly, generation of the enol often is accompanied by "trapping" or masking of the hydroxy group as an ether, such as a silyl enol ether. Diglyme, or bis(2-methoxyethyl) ether, is a solvent with a high boiling point. It is miscible with water. If the R is organic, the compounds are called organic hydroperoxides. Such materials are peer reviewed and may be re‐organized for online delivery, but are not copy‐edited or typeset. [3] Some vinyl ethers also find some use as inhalation anesthetics. Generation of enols often involves removal of a hydrogen adjacent (α-) to the carbonyl group—i.e., deprotonation, its removal as a proton, H+. The conversion of cyclic ketones gives ring-expanded silyl enol ethers.

Ketones contain a carbonyl group (a carbon-oxygen double bond). A Facile Epoxide Aminolysis Promoted by ( In comparison with simple alkenes, enol ethers exhibit enhanced susceptibility to attack by electrophiles such as Bronsted acids.
