Cover Feature: Homolytic N−S Bond Cleavage in Vinyl Triflimides Enabled by Triplet–Triplet Energy Transfer (Chem. Eur. J. 53/2022)

Abstract

Abracadabra! Homolytic bond cleavage enabled by visible‐light‐induced triplet–triplet energy transfer makes us think of a thioxanthone wizard who performs her magic when being excited in the spotlight. She transfers the energy with her wand to the vinyl triflimides thus inducing homolytic N−S bond cleavage to reveal radicals. Just like the divided woman, these recombine leading to α‐quaternary‐β‐trifluoromethylated amines. More information can be found in the Research Article by M. Niggemann and co‐workers (DOI: 10.1002/chem.202201830).

Back in bismuth: controlling triplet energy transfer, phosphorescence, and radioluminescence via supramolecular interactions

“…A Rehm-Weller analysis, 55,56 which incorporates both theoretical and experimental data, was also performed to further support a photoinduced electron transfer using eqn (3),…”

Visible‐Light Promoted Radical Fluoroalkylation of O‐ and N‐Substituted Alkenes

“…Enamines having two triflate groups at the nitrogen atom can undergo extrusion of sulfur dioxide accompanied by migration of the trifluoromethyl group [112] (Scheme 42). This process is similar to that discussed above for vinyl triflates (see Scheme 25).…”
