摘要：

Dehydrogenation of 3,5-disubstituted 4-hydroxystilbenes with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) or alkaline potassium ferricyanide leads to new bisquinone methides which in solution spontaneously dissociate into their monomeric phenoxy radical precursors. Methoxy substitution is found to enhance the homolytic cleavage reaction. The 2,6-disubstituted 4-β-styrylphenoxy radicals are characterized by ultraviolet and electron spin resonance spectroscopy. Oxidation of 2-hydroxy-3-methoxystilbene results in the formation of dimethoxydi-β-styryldiphenoquinone. © 1969, American Chemical Society. All rights reserved.
