摘要：

A simple and efficient preparation of tetrafluorosalicylic acid has been developed which involves a selective substitution of fluorine in pentafluorobenzoic acid with methoxyl group by magnesium methoxide. Tnc: synthesis of 2,6-dimethoxy-3,4,5-trifluorobenzoic acid, 4,5,6-trifluororesorcinol and its dimethoxy ether is described. (C) 1999 Elsevier Science S.A. All rights reserved.
