The oxidation of N-alkyl imines by m-chloroperoxybenzoic acid to yield nitrones was facilitated by (i) the presence of C-aryl substituents, (ii) steric inhibition of attack at the imino C-atom, (iii) electron donating para-substituents on the C-aryl

13C chemical shifts for several series of cis- and trans-N-alkylimines and oxaziridines bearing para-substituted C-phenyl rings are reported and correlated with dual substituent parameters. The 13CN and oxaziridine ring carbon shifts correlate primar

Steric and mesomeric effects have a marked influence upon the formation of oxaziridine (normal pathway) or nitrone (abnormal pathway) products from the imine-peroxyacid reaction; n.m.r. studies of the thermal isomerization of oxaziridines to nitrones

Unexpected equilibrium overshoot observed during the isomerization of the title imine in [2H4]methanol is rationalised in terms of a biased kinetic deuterium isotope effect, and isomerization via an enamine intermediate.

The 1H n.m.r. chemical shift nonequivalence of the ortho-methyl groups in eight title compounds observed at or below ambient temperature is assigned to slow rotation about the aryl–CHMe Bond. The rotational barriers(8–17 kcal mol–1)were evaluat
