Synthesis and some reactions of 3-substituted 2,5-dihydro-2,2, 5,5-tetramethyl-1H-pyrrol-1-yloxyl radicals (nitroxyl radicals, nitroxides) activated with carbonyl, cyano, or ester electron-withdrawing groups have been described. These compounds are useful new SH-reagents for spin-labelling of biomolecules.
