Rate Constants for Termination and TEMPO Trapping of Some Resonance Stabilized Hydroaromatic Radicals in the Liquid Phase

Inhibition of 2‐Amino‐1‐methyl‐6‐phenylimidazo [4,5‐b]pyridine (PhIP) Formation by Alkoxy Radical Scavenging of Flavonoids and Their Quantitative Structure–Activity Relationship in a Model System

“…It is known that TEMPO quenches free radicals (Arends and others ). The addition of TEMPO to the model system decreased the amount of PhIP formed by 92.12 ± 0.71% ( n = 3) compared with the model of creatinine–phenylalanine alone.…”

Transformation of sterically hindered amines (HALS) to nitroxyl radicals: What are the actual stabilizers?

“…In the presence of other radicals, however, they act as very efficient scavengers forming neutral products 37,38) . To determine rate constants of the reactions of nitroxyl radicals, we performed pulse radiolysis experiments with the stable radicals TEMPO (69) and HO-TEMPO (79) and generated radiolytically transient radicals such as alkyl, alkoxyl and alkylperoxy radicals.…”

Nitroxide decomposition: Implications toward nitroxide design for applications in living free‐radical polymerization

“…These unusual properties have led to a wide range of applications spanning their use in biology as spin labels [1][2][3][4][5][6] to the development of organomagnetic materials. 7 In organic chemistry, nitroxides have been used in kinetic studies, [8][9][10][11] as oxidizing species in the form of the corresponding N-oxo ammonium salts, [12][13][14][15][16][17][18][19][20][21][22][23] as temporary caps for transient carbon radicals, [24][25][26][27][28][29][30][31] and as probes for stereocontrol with prochiral carbon radicals. [32][33][34][35][36] In polymer chemistry, nitroxide-mediated polymerization (NMP) [37][38][39][40][41][42][43][44][45][46][47] has become popular as a method for preparing living polymers ...…”
