Stern-Volmer quenching of the photochem. of I indicates that N- and O-abstraction are quenched at different rates . When I is sensitized with triplet sensitizers of increasing ET, N-abstraction increases . These data indicate that N- and O-abstraction in I take place from distinguishable triplet states. Survey of Φp’s of ring-substituted nitrogen-containing heteroaryl ketones (e.g. II; R= H,Me,CN) demonstrates the effect of substitution on the competition between N- and O-abstraction . For methyl- and dicyano-substituted ketones, the results can be understood simply in terms of shifts in ET of the nπ* and ππ* states of the heterocycle. The photochem. of all these ketones requires consideration of interactions among three triplet states.
