3-(4-Cyanophenyl)-2,2-dimethyl-1-phenylpropane-1-thione

The title molecule, C₁₈H₁₇NS, contains an all-trans arrangement of the central aliphatic system and exhibits an intramolecular S...βH contact of 2.71 Å, which is favourable for hydrogen abstraction in a photochemical reaction. The angular parameters (describing the orientation of the H atom relative to the thiocarbonyl plane) are close to those expected for reaction via the (n,π*) excited state.
