Abstract
Photoinduced Electron Transfer Oxygenations of 4-Arylmethylene-1,3(2H,4H)is oquinolinediones afforded oxiranes (5a-5c, 6a-6c, 7) and 1, 3, 4-isoquinoli netriones (8 and 9) as major products in high yields in the presence of tri ethylamine (TEA). These oxygenation reactions are initiated by single elect ron transfer between photoexcited 4-Arylmethylene-1,3(2H,4H)isoquinolinedio nes and TEA, and proceeded via the anion radicals of the substrates.
