Friedel-Crafts-Type Alkylation with Bromodifluoro(phenylsulfanyl)methane through α-Fluorocarbocations: Syntheses of Thioesters, Benzophenones and Xanthones
Bromodifluoro(phenylsulfanyl)methane undergoes a Friedel–Crafts-typealkylation, throughα-fluorocarbocations, with activated aromatic compounds yielding thioesters and/or benzophenones. The methodology has been applied to the synthesis of naturally occurring xanthone derivatives.
