R. Kalgutkar et al., CONVENIENT UNIMOLECULAR SOURCES OF ARYLOXYL RADICALS .3. PHOTOLYSIS OF BIS(ARYLOXY)PHOSPHINE AZIDES, Tetrahedron letters, 35(23), 1994, pp. 3889-3892
Photolysis of sterically hindered bis(aryloxy)phosphine azides in solu
tion, frozen matrix, or neat solid states leads to facile unimolecuIar
production of aryloxyl radicals.
