The effects of intramolecular hydrogen bonding on the electron transfer properties of a series of bisphenol derivatives, as compared with those of monophenol derivatives in which a hydroxy group of the bisphenols is replaced with a methoxy group, have been investigated in relation to
their utility as photothermographic developers. The oxidation of bisphenol derivatives with one-electron oxidants occurs to give the radical cation, followed by deprotonation, to produce the phenoxyl radical. Both the radical cations and phenoxyl radicals have been detected by laser flash
photolysis measurements. Rates of hydrogen transfer reactions from a series of bisphenol derivatives to cumylperoxyl radicals have also been determined by monitoring the decay of the ESR signal of cumylperoxyl radical produced by photoirradiation of an oxygen saturated propionitrile solution
of cumene and di-
