AB - The reactions of 4‐carboxyhydrazide‐5,6‐diphenyl‐3(2H)‐pyridazinone (I) with aromatic aldehydes, phenyl isothiocyanate, β dicarbonyl compounds, ethyl ethoxymethylenecyanoacetate, ethyl cyanoacetate and acylating agents have been investigated. Oxadiazolines (III) and thiazolidinones (IV) were synthesized from arylidenehydrazides (II) through appropriate routes. The thiosemicarbazide derivative (V) on reaction with malonic acid and acetyl chloride gave VII, and on treatment with monochloroacetic acid and sodium acetate afforded IX. Some reactions with 3‐amino‐4,5‐diphenylpyrazolo (3,4‐b) pyridazine (XIVa) were also reported.
