摘要

Abstract 4-tert-Butylphenols can be easily transformed into 4-fluorophenols, provided that no coordinating moiety is present in 2-position, in a two step procedure under mild and safe conditions. The first step leads to 4-tert-butyl-4-fluorocyclohexa-2, 5-dien-1-ones through an oxidative fluorination with [bis (trifluoroacetoxy) iodo] benzene and triethylamine tris (hydrofluoride), and is followed by an acid catalyzed aromatization with loss of isobutene. ...
