## Abstract Eighteen substituted 2‐phenyl‐5,5‐dialkylimidazolinones 2 have been prepared by cyclizations of substituted 2‐(__N__‐benzoylamino)alkanamides 1. The cyclization of methylamides 1 proceeds at room temperature whereas primary amides are cyclized on boiling. The ^1^__H__ and ^13^C nmr spec
Complete proton and carbon NMR assignments were made for five 2-(2X-pbenyl)thiophenes (X = NH, , NO,, COOH, Br), four 2,5diphenylbeterocycles (thiophene, furan and N-methyl-and N-phenylpyrrole) and Nphenylpyrrole using HETCOR, COSY, XCORFE and, in one case, NOESY 2D NMR techniques. In the first set
