N-Fluoro-2,4,6-trimethylpyridinium triflate

See also: N-Fluoropyridinium triflate


Recent Literature


Pd(II)-catalyzed intramolecular amination of arenes using either Ce(SO4)2 as a one- or N-fluoro-2,4,6-trimethylpyridinium triflate as a two-electron oxidant tolerates a wide range of functional groups including acetyl, cyano, and nitro. This catalytic reaction allows expedient syntheses of broadly useful substituted indolines or indoles.

An efficient Z-selective oxidative isomerization process of allyl ethers catalyzed by a cobalt(II) (salen) complex using N-fluoro-2,4,6-trimethylpyridinium trifluoromethanesulfonate (Me3NFPYOTf) as an oxidant provides thermodynamically less stable Z-enol ethers in excellent yields with high geometric control. Diallyl ethers can also be isomerized at room temperature.
