Nickel-catalyzed aminoxylation of an unactivated C(sp3)–H bond with a stable nitroxyl radical has been accomplished for the first time to offer various N-alkoxyamine derivatives, which further enables a one-pot approach to α-formyl acid derivatives. The aminoxylation process reported also provides direct evidence for the oxidative addition of a cyclometallic intermediate with a free radical, which

pathway to α-sulfenylated carbonyl compounds from commercially available thiols and universally employed TEMPO and its analogues, which act as C3 synthons through skeletal rearrangement under simple and metal-free conditions. Mechanism studies suggest that this reaction involves a consecutive radical oxidation and cation coupling process. TEMPO analogues and thiols serve as oxidants and reductive reagents

The present invention generally relates to compounds and methods for inhibiting the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of stable hydroxyl amines to inhibit the polymerization of unsaturated compounds (e.g., vinyl monomers) wherein said stable hydroxylamine is soluble in organic solvents, particularly hydrocarbon solvents consisting of unsaturated and, therefore, polymerizable constituents.
