Abstract

In contrast to triptycene-1,4-quinone (1a), which forms exclusively a di-pi-methane type product when irradiated in acetonitrile, photolysis of the 9,10-dialkyl-substituted triptycene quinones 1b and 1c leads to carbene-derived as well as hydrogen atom abstraction-derived photoproducts. Mechanistic schemes that are capable of rationalizing the results on stereoelectronic grounds are presented and discussed.
