Abstract

Abstract: Irradiation of two families of a-keto phosphates yielded rearrangement products and deprotected phosphates as the major products. For both sets of reactants, the triplet excited state of the ketone reacted with quantum efficiencies that ranged from 0.10 to 0.38. Desyl phosphates yielded 2-phenylbenzo [b] furan independent of the nature of the solvent whereas phosphate esters of a-hydroxy-p-methoxyacetophenone rearranged to esters of ...
