The present application refers to tricyclic sterically hindered alkoxyamines of general formula Ib, their precursors, a process for their preparation and their use as light stabilizers for polymers or coatings, as flame retardants, as peroxide substitutes (rheology modifiers) or carbon radical scavengers.
transformed into bicyclic [(aminocyclopropyl)methyl]alkoxyamines by reaction with various nucleophiles. The products were formed, supposedly via iminium intermediates, in reasonable to high yields, possessing varying degrees of hydrolytic stability. Structural elucidation by NMR spectroscopy strongly suggested an endo position of the amine substituent. The obtained, highly functionalized alkoxyamines
