Both title molecules, C18H26O and C18H26S, contain six-membered cycloh
exane rings with chair conformations, equatorial 1-methyl and 4-tert-b
utyl substituents, and axial 1-benzoyl or 1-thiobenzoyl substituents,
respectively. The substituent carbonyl and thiocarbonyl groups are ori
ented with the O and S atoms close to axial H atoms in the cyclohexane
rings, thus accounting for the observed photochemical reactivity.
