Preparation of (q2-2-Acetyl-4-cyanophenyl)tetra- carbonylmanganese by Reaction of 3-Acetylbenzonitrile with Benzylpentacarbonylmanganese. Four aromatic amidoximes were synthesized by reacting hydroxylamine with 1,3 -dicyanobenzene, 1,4- dicyanobenzene, 3-acetylbenzonitrile, and 4-acetylbenzonitrile. Darzens condensation of 3-acetylbenzonitrile provided aldehyde.
