Cyclic benziodoxole systems have become a premier scaffold for the design of electrophilic transfer reagents. A particularly intriguing aspect is the fundamental II–IIII tautomerism about the hypervalent bond, which has led in certain cases to a su

The reaction of nucleophilic tertiary amines with trifluoromethyl and pentafluoroethyl methyl ethers provides quaternary ammonium trifluoromethoxide (NR4OCF3) and pentafluoroethoxide (NR4OCF2CF3) salts, respectively, in good yields. The new trifluoro

A synthetic method for the palladium-catalyzed cyanation of aryl boronic acids using bench stable and non-toxic N-cyanosuccinimide has been developed. High-throughput experimentation facilitated the screen of 90 different ligands and the resultant st

The first light-driven method for the alpha-trifluoromethoxylation of ketones is reported. Enol carbonates, in particular Boc derivatives, react with N-trifluoromethoxy-4-cyano-pyridinium triflimide (2a) using the photoredox-catalyst 4-CzIPN (5 mol-%

The first light-driven method for the α-trifluoromethoxylation of ketones is reported. Enol carbonates react with N-trifluoromethoxy-4-cyano-pyridinium, using the photoredox catalyst 4-CzIPN under 456 nm irradiation, affording the α-trifluoromethox

In this Review, we highlight recent advances in the understanding and design of N-functionalized pyridinium scaffolds as redox-active, single-electron, functional group transfer reagents. We provide a selection of representative methods that demonstr

Electron-transfer photocatalysis provides access to the elusive and unprecedented N-pyridyl radical cation from selected N-substituted pyridinium reagents. The resulting C(sp2 )-H functionalization of (hetero)arenes furnishes versatile intermediates

A perfluoroisopropenyl ether terminated oligo(hexafluoropropylene oxide), a perfluoropolyalkyl ether macromonomer for radical copolymerization, has been prepared. The synthesis was achieved through a carefully controlled defluorination of a highly un
