  Dialkylzinc-mediated allylic polyfluoroarylation reaction

  摘要：

  We present an allylic polyfluoroarylation reaction with broad substrate scope and excellent functional group tolerance, using organozinc reagents under mild conditions. A catalytic amount of triphenylphosphine oxide efficiently promotes iodine-zinc exchange reaction between polyfluoroaryl iodide and dimethylzinc, and the resulting phosphine oxide-activated polyfluoroarylzinc undergoes substitution reaction with allylic halides to afford the corresponding polyfluoroarylated products.

  A palladium-catalyzed allylic C–H arylation reaction with electron-deficient arenes with high regio- and stereoselectivity is reported. This work represents the first successful use of 1,1′-bi-2-naphthol as the ancillary ligand in allylic C–H activation, which is the key factor for chemoselectivity. Furthermore, high selectivity allylic C–H acetoxylation and amination were also successfully achieved
