Reinvestigation of the Behaviour of Benzal-anils towards the Action of Potassium Cyanide

Reinvestigation of the behaviour of benzal-anils (1) towards the action of potassium cyanide was found to give a mixture of 4-imidazolidinone (6) and 4-imidazolone (7). 6 was also obtained by benzaldehyde addition to α-arylamino-α-phenylacetonitrile (7) or by condensation of benzaldehyde with α-phen...

Zusammenfassung:Reinvestigation of the behaviour of benzal-anils (1) towards the action of potassium cyanide was found to give a mixture of 4-imidazolidinone (6) and 4-imidazolone (7). 6 was also obtained by benzaldehyde addition to α-arylamino-α-phenylacetonitrile (7) or by condensation of benzaldehyde with α-phenylamino-α-phenylacetamide (8). The partial conversion of 6 and 7 to each other was discussed.
