Oxidation of 1,2-Bis(hydroxylamines)

Dixon, Dabney White,Weiss, Randy H.

, p. 4487 - 4494 (2007/10/02)

Oxidations of 1,2-bis(aminooxy)ethane (H2NOCH2CH2ONH2) and its phenyl substituted derivative (H2NOCHPhCH2ONH2) give a variety of products.Some are consistent with formation of the 1,4,2,3-dioxadiazene ring or a polymeric hyponitrite, while others derive from separate oxidation of the two ends of the hydroxylamine.Nitrogen yields are ca. 60percent in nickel peroxide oxidations and ca. 25percent in tert-butyl hypochlorite oxidations.
