Vinyl group - Wikipedia
In organic chemistry, a vinyl group (abbr. Vi; [1] IUPAC name: ethenyl group[2]) is a functional group with the formula −CH=CH2. It is the ethylene (IUPAC name: ethene) molecule (H2C=CH2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH2 where R is any other group of atoms.

Why are "vinylic" and "allylic" carbons named so?
2023年9月24日 · Knowing the origin of the terms won't help you to identify what carbon is "allyic" or "vinylic". A vinyl group is a functional group with the formula $\ce{−CH=CH2}$ and allyl group is vinyl group but an extra methylene bridge ( $\ce{-CH2}$ ), so it is $\ce{−CH2−HC=CH2}$ .
Illustrated Glossary of Organic Chemistry - Vinylic hydrogen
Vinylic hydrogen: A hydrogen atom bonded to an sp2 carbon of an alkene. The vinylic hydrogens are shown in red. None of the other hydrogens are vinylic.
What is the Difference Between Allylic and Vinylic Carbons
2024年9月18日 · Vinylic hydrogen is directly attached to a carbon atom that is part of a double bond. Allylic hydrogen is attached to a carbon atom adjacent to a double bond. This is the structural difference between vinylic and allylic hydrogen.
Vinylic Hydrogens - (Organic Chemistry) - Vocab, Definition
Vinylic hydrogens refer to the hydrogen atoms attached to the carbon-carbon double bond in alkene molecules. These hydrogens exhibit distinct chemical and spectroscopic properties that are crucial in understanding the uses of 1H NMR spectroscopy.

2024年5月24日 · Transition metal catalysis allows for the efficient and selective introduction of vinyl moieties onto organic molecules and offers a versatile approach to synthesizing complex organic molecules.
Vinyl cation - Wikipedia
Aside from protons, other electrophilic groups can attack an acetylene moiety. When attacked by carboxylic acids, cis/trans alkene adducts may be formed. The reaction with hydrogen halides, which also has an initial protonation step, results in the formation of halo-substituted alkenes.
Vinylic - (Organic Chemistry) - Vocab, Definition, Explanations
A vinylic position in organic chemistry refers to the position of a hydrogen or substituent that is directly attached to an alkene's sp^2 hybridized carbon atom. This term is often used when discussing reactions involving the addition of elements across the double bond of alkenes.
Vinyl hydrogen - Big Chemical Encyclopedia
