N2 - α-Alkyl dibenzyl ketones that are capable of undergoing both Norrish Type I and Type II reactions generally yield products of Norrish Type I reaction in organic solvents. These water insoluble ketones form water-soluble host-guest complexes with β and γ-cyclodextrins. Irradiation of the above β-cyclodextrin complexes in water leads to products of Norrish Type II reaction. This change in behavior between the guest alone in organic solvent and as host-guest complexes in water is consistent with the influence of other ordered media such as micelles and reactants such as benzoin alkyl ethers and alkyl deoxy benzoins.
