Abstract:
The non-bonded S...O intramolecular interactions in the title compounds 2-(phenylthio)acetophenone [IUPAC: 2-[2-(phenylsulfanyl)phenyl]ethanone], C(14)H(12)OS, and 2-(benzylthio)acetophenone [IUPAC: 2-[2-(benzylsulfanyl)phenyl]ethanone], C(15)H(14)OS, are unusually short, indicating the contribution of heterocyclic oxathiole-type resonance structures to the overall bonding.

The reaction begins with an attack of the nucleophile on the carbon that holds the leaving group. This results in the delocalization of the π electrons over the ring carbons. The resonance interaction between the...

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
