Hydrazones of further mono- and especially di-carbonyl compounds have been studied. That of acetonylacetone gave hexa-2,5-diene, and that of biphenacyl gave diphenylbutadiene with much 3,6-diphenylpyridazine. Hydrazones of αβ-unsaturated aldehydes and ketones gave pyrazoles, also obtained under the same conditions from 1-toluenesulphonylpyrazolines. Hydrazones of ω-substituted acetophenones, PhCO·CH2X
