PHOTOLYSIS OF 2-ARYLOXY- OR 2-ARYLTHIO-1,3-BENZODIOXAN-4-ONES

Photolysis of 1,3-benzodioxan-4-ones 3b and 4a gives mainly products derived from photorearrangement, photoreduction and/or photosolvolysis.These results closely parallel those obtained by irradiation of the isomeric open-chain compounds 1b and 2a.A mechanism involving the intermediacy of radical pairs A and B, generated by successive homolysis of the aryloxy- or arylthio-carbon and carbonyl-oxygen bonds, is proposed.
