PROCESSO PARA A OBTENCAO DE SUBSTANCIAS AROMATICAS FLUORADAS SUBSTITUIDAS EM POSICAO ORTO

摘要

Ortho-substituted fluoroaromatic compounds are prepared by reaction of corresponding anilines, which are substituted in the o-position, with alkyl nitrites in the presence of alcohols and/or ethers and in the presence of boron trifluoride or boric acid esters and hydrogen fluoride, and by isolation and decomposition of the diazonium tetrafluoborate produced.
