Abstract A number of 1-alkyl-2-carboazetidines have been prepared from the reaction of primary amines with α, γ-dibromocarbonyl compounds. Several of these new azetidines exhibit doublet carbonyl stretching absorptions in their infrared spectra. A possible explanation of this phenomenon is offered in terms of three rotational conformers which represent various degrees of dipole-dipole and steric interactions. The cis and trans forms ...
