The incorporation of nitrogen in the phenolic ring leads to compounds with very low phenolic O-H bond dissociation enthalpies, and thus high reactivities towards peroxyl radicals, but which are reasonably stable to direct reactions with air. The 3-pyridinols 1 and 2 are extremely effective peroxyl-radical-trapping chain-breaking antioxidants.

Abstract
The incorporation of nitrogen in the phenolic ring leads to compounds with very low phenolic O-H bond dissociation enthalpies, and thus high reactivities towards peroxyl radicals, but which are reasonably stable to direct reactions with air. The 3-pyridinols 1 and 2 are extremely effective peroxyl-radical-trapping chain-breaking antioxidants.File in questo prodotto:
