Abstract

The 15N NMR chemical shifts and 1(15N-1H) coupling constants of a series of imidazolidine-2,4-dichalcogen (O, S) derivatives are reported.The 15N NMR chemical shifts show a linear correlatlon wlth the vNH stretchlng vlbratlons. The influence of the substitution of the oxygen at C2 and/or C4 with the sulphur, and of the hydrogen at C5 wlth the methyls and phenyls has been considered. The 1J(15N-1H)'s found In thls serles of molecules agrees well with the expected values.
