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.

An industrially important example is vinyl chloride, precursor to PVC, [3] a plastic commonly known as vinyl. Chessboard made from polyvinyl chloride. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp 2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups.

[citation needed] It can be derived from vinylic systems and terminal acetylenes by using a configuration-retention stereospecific procedure such as the Sonogashira reaction. Vinyl iodides are the most reactive vinyl halides to Pd 0 oxidative addition, and their use is therefore most frequent for Sonogashira cross-coupling reactions due to the ...

Vinylogous reactions also include conjugate additions, where a nucleophile reacts at the vinyl terminus, akin to the addition of the nucleophile to the carbonyl of the methyl ketone. In a vinylogous variation of the aldol reaction, an electrophile is attacked by a nucleophilic vinylogous enolate (see first and following image). The vinylogous ...
