title: A direct catalytic ring expansion approach to o-fluoronaphthols and o/p-fluorophenols from indanones and 2-cyclopentenones.
abstract: A direct method for the synthesis of o-fluoronaphthols and o/p-fluorophenols has been developed by a catalytic ring expansion of indanones and 2-cyclopentenones, in which TMSCF2Br was used as a unique :CF2 source, a TMS transfer agent, as well as the Br(-) and F(-) releaser for the enolization, difluorocyclopropanation, desilylation, ring opening, defluorination, and aromatization sequence.
