Identification of Phenyl Vinyl Ketone And Related Compounds as 2,4-Dinitrophenylhydrazones and Pyrazolines

Abstract

The closely interrelated, titled compounds, which have similar physical properties and which form mixtures difficult to separate, are best characterized by instrumental methods.All α,β-unsaturated aldehydes and methyl ketones gave open-chain dinitrophenylhydrazones directly, whereas the arylated ketones form pyrazolines, as is well known.
