Abstract
Eighteen substituted 2-phenyl-5,5-dialkylimidazolinones 2 have been pr epared by cyclizations of substituted 2-(N-benzoylamino)alkanamides 1. ?he cyclization of methylamides 1 proceeds at room temperature wherea s primary amides are cyclized on boiling. The H-1 and C-13 nmr spectra of the imidazolinones are presented and the changes in their spectra connected with their protonation in hexadeuteriodimethyl sulfoxide-tri fluoroacetic acid mixtures are discussed.
