Transmission of electronic effects through a system of conjugated chemical bonds
In organic chemistry, vinylogy is the transmission of electronic effects through a conjugated organic bonding system. The concept was introduced in 1926
Vinylogy
System of connected p-orbitals with delocalized electrons in a molecule
engage in spiroconjugation or in homoconjugation across the spiro atom. Vinylogy is the extension of a functional group through a conjugated organic bonding
