Photosensitisation in the photolysis of saturated ketones
Abstract
The cyclobutanol : fragmentation ratio was measured for the Type II photoreactions of cis-2-propyl-4-t-butylcyclohexanone as a function of solvent. The ratio measured for acetone as a solvent is the same as that for the reaction taking place entirely in the triplet state. It is concluded that acetone can photosensitise the triplet state reactions of saturated ketones.
