Nitrosation of hydroxylamine

Furoxanes 321 can be prepared from amide oximes in one step by nitrosation of hydroxylamines in the presence of H2S04 (Equation 70) <2002RCB1504>. [Pg.379]

The mechanism and kinetics of nitrosation of hydroxylamines has been discussed recently [65a-c],... [Pg.479]

Earlier work on the nitrosation of hydroxylamines showed that a similar mechanism was operating the positive nitrosating species attacked the oxygen atom of the protonated derivative RNH2OH, and this was followed by a migration of NO from O to N (M. N. Hughes et al., 1968). [Pg.388]

Among examples studied are the nitrosation of hydroxylamine and its methyl derivatives (M. N. Hughes et al., 1968), hydrazine (Perrott et al., 1976) and the methylhydrazines (Perrott et al., 1977). In all cases reaction occurred via the conjugate acid of the substrate, and although thiocyanate ion catalysis is more pronounced than that of bromide ion, the second order rate constants for reaction (25) were found to be approximately 100 times less than for nitrosyl bromide. More recent work with both morpholine and aniline showed the... [Pg.399]
