METHOD FOR PREPARING A META-DIHYDROXYLATED AROMATIC COMPOUND

摘要

A method for preparing a meta-dihydroxylated aromatic compound, and more particularly for preparing resorcin or 1,3-diphenol is described. The preparation of a meta-dihydroxylated aromatic acid as an intermediate is also described. The method for preparing a meta-dihydroxylated aromatic compound includes the steps of successively or simultaneously hydroxylating and decarboxylating an aromatic compound bearing one or more carboxylic and/or carboxylate groups and, on either side, in the ortho position, a hydroxyl group and a hydrogen atom.
