Effects of Intramolecular Hydrogen Bond on Electron Transfer Oxidation of Bisphenol Derivatives

Abstract

Electron transfer properties of a series of bisphenol derivatives were examined to clalify the effects of intramolecular hydrogen bonding on the electron transfer. The electron transfer oxidation of bisphenols occurrs via formation of the radical cation and the deprotonated phenoxyl radical. The ESR spectra of phenoxyl radicals derived from bisphenol derivatives indicate formation of an intramolecular hydrogen bond. The formation of the intramolecular hydrogen bond facilitates the electron transfer oxidation of bisphenol derivatives.
