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 (Me3NFPY•OTf) 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.
