Regiochemistry of mercury(II) oxide oxidation of unsymmetrical N,N-disubstituted hydroxylamines

Ali, Sk. Asrof,Hashmi, S. M. Azhar,Siddiqui, Mohammad N.,Wazeer, Mohammed I. M.

, p. 14917 - 14928 (1996)

Mercury(II) oxide oxidation of N,N-disubstituted hydroxylamines with the α and α' carbon atoms containing one and two hydrogen atoms, respectively, gave aldonitrones in a highly regioselective manner. Removal of the α proton is involved in the rate determining step as shown by primary kinetic isotope effect.
