SYNTHESIS OF 4,5-DIHYDROXYBENZOFURANS AND 4,5-DIHYDROXYINDOLES BY DEHALOGENATION OF HALO DERIVATIVES

A preparative method for the synthesis of derivatives of 4,5-dihydroxybenzofuran and 4,5-dihydroxyindole by dehalogenation of 4,5-dihydroxy-6-chloro (or bromo) and 4,5-dihydroxy-6,7-dichloro derivatives of benzofuran and indole with heating in aqueous eth
