Carbonyl group - Wikipedia
In organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group ) 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 … See more Vinyl derivatives are alkenes. If activated by an adjacent group, the increased polarization of the bond gives rise to characteristic reactivity, which is termed vinylogous: • In See more • Acetylenic • Allylic/Homoallylic • Alpha-olefin • Benzylic • Propargylic/Homopropargylic See more The radical was first reported by Henri Victor Regnault in 1835 and initially named aldehydène. Due to the incorrect measurement of the atomic mass of carbon it was believed to be C4H6 at the time. Then in 1839 it was renamed by Justus von Liebig See more Web1-methyl-2- (methylsulfonyl)benzimidazole reacts with a variety of aldehydes and ketones in the presence of either NaHMDS (-55 °C to rt) or t -BuOK (rt, 1 h) in DMF to give the … WebThe terminal alkyne produced after double dehydrohalogenation is deprotonated by sodium amide, and the third mole of the base is to ensure that the deprotonation occurs … hawthorn player list 2022
