Experiments were first conducted with acetic and polyphosphoric acids, and with several concentrations of H2SO4. As expected for a methyl ketone, with 1-phenyl-2-propanone phenylhydrazone use of PPA catalyst resulted in a large variation in isomer ratio (see Table 1). With 3-heptanone the variations resulting from use of different acids were much smaller. Of several active zeolite catalysts tested, H-beta was found to be the most selective heterogeneous catalyst for the synthesis of the linear isomer from 3-heptanone and l-phenyl-2-butanone phenylhydrazones whereas, in contrast, H-Na-Y gave about equal amounts of both isomers.

Experiments to synthesize six membered heterocycles starting from both l,3-diphenyl-2-propanone phenylhydrazone and 2-ethoxy-l-naphth-aldehyde semicarbazone, which are unable to form five membered rings, faded [692]. 

Preparation 251.—Phenylhydrazone oi Pyruvic Acid [Propanon-add-phenylhydrazone]. 

In saccharides, cleavage by periodic acid or sodium periodate occurs between any carbons possessing/ree hydroxy lie groups. Thus glucosazone treated with periodic acid in aqueous ethanol at room temperature is degraded to the l,2-bis(phenylhydrazone) of mesoxalaldehyde (propanone-dial) in 85% yield [759].
