Organic synthesis using nitroxides

D Leifert, A Studer - Chemical Reviews, 2023 - ACS Publications
Nitroxides, also known as nitroxyl radicals, are long-lived or stable radicals with the general
structure R1R2N–O•. The spin distribution over the nitroxide N and O atoms contributes to …

The persistent radical effect in organic synthesis

D Leifert, A Studer - Angewandte Chemie International Edition, 2020 - Wiley Online Library
Radical–radical couplings are mostly nearly diffusion‐controlled processes. Therefore, the
selective cross‐coupling of two different radicals is challenging and not a synthetically …
