A palladium-catalyzed fluoroalkylative cyclization of olefins with readily available Rf-I reagents to afford the corresponding fluoroalkylated 2,3-dihydrobenzofuran and indolin derivatives with moderate to excellent yields is reported. This novel procedure provides an efficient method for the construction of Csp3-CF2 and C-O/N bonds in one step. A wide range of functional groups are tolerated. It is proposed that a radical/SET (single electron transfer) pathway proceeding via the fluoroalkyl radical may be involved in the catalytic cycle.

Phenols were converted to salicylaldehydes with paraformaldehyde, MgCl2-Et3N in THF, and subsequent treatment with aqueous ammonia gave the corresponding imines which were oxidized with IBX to the desired salicylnitriles. The sequence of reactions was conveniently carried out as a one-pot procedure under mild conditions.

Mono-substituted 2-methylbenzo[b]furans were prepared by Claisen rearrangement of corresponding allyl phenyl ethers and subsequent bis(benzonitrile)palladium(II) chloride-mediated cyclization of o-allylphenols.
