Abstract

The 13C chemical shifts for the cis- and trans-N-substituted diphenyl, dibenzoyl, aroylaryl, and arylcyanoaziridines (1-8) have been reported (Table 1, 2, and 3). The differences of 13C chemical shifts between the cis and trans isomers and the effects of N- and ring C-substituents, and of the para-substituted groups of phenyl or benzoyl group upon the chemical shifts of the ring carbons are described. The chemical shifts of the ring carbons are qualitatively discussed in terms of steric compression effects.
