Crystal structure-reactivity relationships in the solid state photochemistry of 2,4,6-triisopropylthiobenzophenone: C=O...H versus C=S...H abstraction geometry

X-ray crystal structure solid state photoreactivity correlations are reported for 2,4,6-triisopropylthiobenzophenone (1a) and its p-methoxy derivative 1b. The results reveal interesting differences in the geometry of gamma-hydrogen atom abstraction for ketones and thiones.
