Photolysis of N-methylphenanthrene-9,10-dicarboximide (PI) with diethylamine (1a) in benzene gave an aminolysis product together with reduction-products and other coupling products. Effects of addition of 1-propanethiol and concentration of 1a indicate that the aminolysis appears to arise from N–H abstraction mainly by excited triplet state of PI.
