incorporated in a six-membered (1,3,2-dioxaphosphorinane) ring. This mechanism is contrasted to that for the previously reported triplet-sensitized photorearrangements of phosphites 1 and 7, which have greatly different phi P values. For these reactions, kinetic formation of the triplet analogue of 21, but without the tert-butyl substituent, requires a permutation of substituents for conversion to diradical
