Vinylogy
Vinylogy has been defined as the transmission of electronic effects through a conjugated organic bonding system. The concept was introduced in 1926 by Ludwig Claisen to explain the acidic properties of formylacetone and related ketoaldehydes. Its adjectival form, vinylogous, is used to apply the concept of vinylogy taught in intermediate undergraduate through graduate/research organic chemistry. To be specific, the concept describes structures and reactivity that involve an atom attached via a carbon-carbon double bond to a further electropositive atom/group. Vinylogous reactivity is the modified behavior observed of the atom/group that is attached via the double bond, which is therefore in conjugation with the electropositive center — where the attached group's reactivity is observed to be analogous to reactions with the EWG itself. For instance, an hydroxyl group attached directly to a carbonyl is by definition a carboxylic acid that can ionize by loss of the proton from the hydroxyl group with an equilibrium constant termed the acid's pKa, a numerical value that reflects the acid's strength. Likewise, when a hydroxyl group is "indirectly" attached to a carbonyl via an intervening vinyl moiety, it is termed a vinylogous carboxylic acid, and it also ionizes by loss of a proton, and with an equilibrium constant very similar to that of the analogous parent carboxylic acid.
