Abstract
Upon irradiation, 2-benzoyl-2-methylcyclohexanone gave 4-benzoyl-2-methylcyclohexanone via Type II cyclization and a subsequent ring opening in 79% yield, whereas 2-benzoylcyclohexanone gave only the Type II elimination product. 2-Benzoyl-2-methyl-1-tetralone also underwent phototransformation to 4-benzoyl-2-methyl-1-tetralone.Keywords
