In organic chemistry, vinylation is the process of attaching a vinyl group (CH 2 =CH−) to a substrate. Many organic compounds contain vinyl groups, so the process has attracted significant interest, especially since the reaction scope includes substituted vinyl groups. The reactions can be classified according to the source of the vinyl group.
Chemical structure of the vinyl functional group. In organic chemistry , a vinyl group (abbr. Vi ; [ 1 ] IUPAC name : ethenyl group [ 2 ] ) is a functional group with the formula −CH=CH 2 . It is the ethylene (IUPAC name: ethene) molecule ( H 2 C=CH 2 ) with one fewer hydrogen atom.
Vinyl chloride is an organochloride with the formula H 2 C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic.
Vinyl chloride is produced by dehydrochlorination of 1,2-dichloroethane. [1] Due to their high utility, many approaches to vinyl halides have been developed, such as: reactions of vinyl organometallic species with halogens; Takai olefination; Stork-Zhao olefination with, e.g., (Chloromethylene)triphenylphosphorane - a modification of the Wittig ...
Vinyl products are pervasive—including toys, [50] car interiors, shower curtains, and flooring—and initially release chemical gases into the air. Some studies indicate that this outgassing of additives may contribute to health complications, and have resulted in a call for banning the use of DEHP on shower curtains, among other uses.
Vinyl alcohol, also called ethenol (IUPAC name; not ethanol) or ethylenol, is the simplest enol. With the formula C H 2 CH O H , it is a labile compound that converts to acetaldehyde immediately upon isolation near room temperature. [ 1 ]
The vinyl cation is a carbocation with the positive charge on an alkene carbon. Its empirical formula of the parent ion is C 2 H + 3.Vinyl cation are invoked as reactive intermediates in solvolysis of vinyl halides, [1] [2] as well as electrophilic addition to alkynes and allenes.
Vinyl sulfone functional group ("R" is an arbitrary structure) In organic chemistry , a vinyl sulfone is a functional group consisting of a vinyl group bonded to a sulfone group. Specific compounds containing this functional group are divinyl sulfone, [ 1 ] phenyl vinyl sulfone, [ 2 ] methyl vinyl sulfone, [ 3 ] and ethyl vinyl sulfone.
