摘要

In the absence of nucleophilic agents O-hydroxybenzyl alcohols through the formation of O-methylenequinones suffer di- and trimerization by [4+2]-cycloaddition. At the same time the cases of formal [4+4]-cycloaddition of O-mefhylenequinones are extremely seldom. We showed that the sterically hindered 2-(2-hydroxyphenyl)-2-adamantanol (I) at a temperature higher than the melting point (>160°C) underwent a dimerization into 6H,12H-dibenzo[b,f]dioxocine (II).
