Electrophilically catalysed cleavage of the N-0 bond of N,N-dimethoxyamine results in the formation o f singlet N-methoxynitrenium ion, which aminates soft nucleophiles, methylates hard ones, and epiminates alkenes.Two electronegative N-substituents in N,N-dialkoxyamines' amines and N-alkoxyamines. However, N,N-dialkoxyamines significantly decrease the p character of the nitrogen lone undergo reactions typical for ~~o n d a r y amines; hydroxy-and electron pair. Therefore, these compounds are characterized amino-methylation,' acylation and carbamoylation,2 and by a higher pyramidal stability [AGfn,, -20 kcal mol-1(1 cal = N-~hlorination.~ They are also easily oxidised forming stable 4.184 J)]' and weaker nucleophilicity 1 compared to common N,N-dialkoxyaminYl radicals.4
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
