SYNTHESIS OF 2,2′-DIHYDROXYBIPHENYL DERIVATIVES
Abstract
Synthesis of 2,2′-dihydroxybiphenyl-4,4-dicarboxylic acid by alkaline fusion of 1-nitro- and 1-methoxy substituted 5,5-dioxodibenzothiophene-3,7-dicarboxylic acids has been investigated. It has been shown that along with dibenzothiophene ring opening and formation of biphenyls, a cyclization reaction also occurred. Small amounts of dibenzofuran-3,7-and 4-hydroxycarbazole-2,7-dicarboxylic acids have been found among products of the reaction. New luminescent dyes based on 2,2′-hydroxybiphenyls have been synthesized.
