A spectroscopic study of some arylimidate compounds

Abstract

A spectroscopic study of 25 arylimidate compounds has been carried out. The assignments were arrived at by comparing the spectra of the arylimidates and the products of rearrangement of the N-aryl substituted compounds. Spectra of several related esters were examined to enable a description of the skeletal modes of the imidates to be obtained.

The dipole moments of the simpler imidates and some related esters were measured for comparison and in order to obtain structural information about the imidates.

Temperature studies were performed on the (C=N) absorption of some imidates. Ultra violet and nuclear magnetic resonance spectra of the imidates were recorded in an attempt to obtain information on the electronic nature of the aryl rings and the (C=N) group.

Some anilides were examined by dielectric and infrared techniques to obtain structural information. 15 previously unmeasured dipole moments were measured during the course of this study.
