Abstract
The Norrish type I and type II reactions of cyclodextrin-included \alpha-alkyldibenzyl ketones were examd. in aq. soln. and in the solid state. The photolysis of solid cyclodextrin complexes led to a single product, diphenylethane, and that of complexes in aq. soln. gave a product arising from the rearrangement of \alpha -alkyldibenzyl ketones. Conformational and super-cage effects are proposed to be responsible for this photobehavior. The difference in the products from solid and soln. complexes is attributed to the differences in the restriction imposed by the host on the translational motions of the geminate radical pairs.
