Temperature effect on photochemical reactions of ortho-alkylphenacyl benzoates, one of the recently developed photoremovable protecting groups (PPG), giving indanones (IN) and benzocyclobutenols (CB) was examined. As temperature was lowered, CB was formed preferentially over IN and the amount of IN increased as temperature was elevated. Arrhenius plot of ln(IN/CB) versus 1/T gave a straight line from which EaIN-EaCB and A IN/ACB were obtained. The least sterically hindered 2-methylphenacyl benzoate (1) gave the highest EaIN-EaCB and AIN/ACB among the ortho-alkylphenacyl benzoates tested in this research including 2,4,6-trimethylphenacyl benzoate (2) and 2,4,6-triisopropylphenacyl benzoate (3).

Photolysis of 2,4,6-trialkylphenacyl benzoates gives not only the corresponding indanones and benzoic acid, but also the corresponding benzocyclobutenols (CBs), which are also detected in the photolysis of mono-alkylphenacyl benzoates for the first time.
