in the presence of equimolecular amounts of N-arylcarbonimidoyl dichlorides, provides a new and very convenient method for the synthesis of 3,4,5-triaryl-2-aryliminooxazolines. Geometrical characteristics of this little known class of heterocycle were determined by X-ray crystallography of 2-(4-chlorophenylimino)-5-(4-methoxyphenyl)-3-(4-methylphe-nyl)-4-phenyloxazoline.
