Temperature effects in the photochemistry of cycloalkanones in solution

Abstract

The effect of temperature changes on product ratios in the photochemical reactions of cycloalkanones is discussed. Data obtained for α-cleavage products and photoelimination products from monocyclic cyclopentanones and cyclohexanones at different temperatures are consistent with previously suggested reaction mechanisms. The need for closer temperature control in quantitative photochemical investigations is emphasised.
