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.
On a carbon skeleton, sp 2-hybridized carbons or positions are often called vinylic. Allyls , acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called divinyl benzene .)
α,β-Unsaturated carbonyl compounds featuring a carbonyl conjugated to an alkene that is terminal, or vinylic, contain the acryloyl group (H 2 C=CH−C(=O)−); it is the acyl group derived from acrylic acid. The preferred IUPAC name for the group is prop-2-enoyl, and it is also known as acrylyl or simply (and incorrectly) as acryl. Compounds ...
A compound is a carbon acid if deprotonation results in loss of a proton from a carbon atom. Compared to compounds typically considered to be acids (e.g., mineral acids like nitric acid , or carboxylic acids like acetic acid ), carbon acids are typically many orders of magnitude weaker, although exceptions exist (see below).

At room temperature, acetaldehyde (H 3 CC(O)H) is more stable than vinyl alcohol (H 2 C=CHOH) by 42.7 kJ/mol. [3] Vinyl alcohol gas isomerizes to the aldehyde with a half-life of 30 min at room temperature.

The C–H bonds of allenes are considerably weaker and more acidic compared to typical vinylic C–H bonds: the bond dissociation energy is 87.7 kcal/mol (compared to 111 kcal/mol in ethylene), while the gas-phase acidity is 381 kcal/mol (compared to 409 kcal/mol for ethylene [16]), making it slightly more acidic than the propargylic C–H bond ...
