1-Methyl-3-phenylsulfonyl-2-piperidone

Abstract

The piperidone ring in the title compound, C12H15NO3S, has a slightly distorted half-chair conformation with the methyl, carbonyl and phenylsulfonyl ring substituents occupying equatorial, equatorial and axial positions, respectively. Molecules are connected into centrosymmetric dimers via C—H...O interactions and these associate into layers via C—H...O—S contacts. Further C—H...O interactions involving both the carbonyl and sulfonyl O atoms consolidate the crystal packing by providing connections between the layers.
