Propargylic, allylic and benzylic alcohols prove to be fairly successful as activated nucleophiles, under mild conditions for the SNAr reaction.
在SNAr反应的温和条件下,炔丙基、烯丙基和苄基醇证明作为活化的亲核试剂相当成功。

A highly efficient palladium-catalysed phenyl diazonium tetrafluoroborate participation of C-H activation ring closure protocol has been developed. A series of 6H-benzo[c]chromenes have been synthesized by intramolecular cyclization of ortho diazonium salts tetrafluoroborate of benzyloxyphenyl (Method A), or phenoxymethyl phenyl (Method B). The transformation allows the synthesis of 6H-benzo[c]chromenes with a wide variety of functional groups and substitution patterns from simple and easily accessible precursors.
