1,2‐ and o‐dioxo compounds condense with phenylhydrazine in mineral acid solution to give yellow phenyl osazones. The non quinoidic 1,2‐dioxo compounds condense with ammonia and formaldehyde to give imidazoles which, as tertiary amines, show the Ohkuma color reaction with citric acid and acetic anhydride. Spot tests for pertinent dioxo compounds were developed on the basis of these facts.
