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 1H and 13C nmr spectra of the imidazolinones are presented and the changes in their spectra connected with their protonation in hexadeuteriodimethyl sulfoxide-trifluoroacetic acid mixtures are discussed.

A novel process for the preparation of 2-(5,5-disubstituted-4-oxoor thiono)-2-imidazolin-2-yl)nicotinic acids, quinoline-3-carboxylic acids and benzoic acids by the base-catalyzed cyclization of appropriately substituted 2-carbamoyl nicotinic acids, 3-quinolinecarboxylic, or benzoic acids. The products are useful as herbicides.
