X-ray crystallographic studies of derivatives of N-methoxy- and N-tert-butoxy-2,2,6,6-tetramethylpiperidine show that as expected the N-O bond is staggered with respect to the C-H bonds of the methoxy group in the former case, yet it eclipses a C-methyl b

The reaction of stable sterically hindered nitroxyl radicals with benzylic and allylic substrates was investigated. An allyloxyamine derivative was obtained by the reaction of 2 molar equiv of a nitroxyl radical with an unactivated alkene. Experimental an
Prevention of oxidation in petrochemical extraction solvents

, (2008/06/13)
A wide variety of hindered amine compounds are effective as antioxidant stabilizers to prevent the oxidation of liquid hydrocarbons and of oxygenated compounds, such as sulfolane or tetraethylene glycol, used as extraction solvents in the petroleum industry.
