## 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

✦ Synopsis
NMR-Spectra of 1-[2,4,5-triphenyl-2-cyclopentenyl]phenyl ketone and 1-[2,4,5-triphenyI-1 -cyclopentenyl]phenyl ketone indicate that the coupling constants of vicinal hydrogens in the cyclopentene ring vary with structure.
