Chemie der Amino‐oxime, XIV. Synthese und Reaktionen von 2‐[α‐(E)‐(Hydroxyimino)benzyl]‐3‐imidazolin‐3‐oxiden

The Chemistry of Amino Oximes, XIV Synthesis and Reaction of 2‐[α‐( E )‐(Hydroxyimino)benzyl]‐3‐imidazoline 3‐Oxides 2‐Benzoyl‐4‐phenyl‐1‐( p ‐tolyl)‐3‐imidazolin 3‐oxide ( 3b ) has been prepared by cyclocondensation of α‐( p ‐toluidino)acetophenone oxime ( 1a ) with phenylglyoxal and transferred into 2‐[α‐( E )‐(hydroxyimino)benzyl]‐4‐phenyl‐1‐( p ‐tolyl)‐3‐imidazoliune 3‐oxide ( 5a ). 5a is identical with the product prepared by oxidation of 1a , with FeCl 3 .
