Synthesis of 3-arylazo-6-oxopyridazin-5-carbonitriles: A versatile precursor for condensed arylazopyridazin-6-ones

(Chemical Equation Presented) 1-[2-Phenyl-1-diazenyl]-1-[2-phenylhydrazono] acetone or 1-[-2-(4-methylphenyl)-1-diazenyl]-1-[-2-(4-methylphenyl)hydrazono]- butan-2-one were produced via coupling the (E) 2-oxopropanal-1-phenyl-hydrazone or (E) 2-oxobutanal

Studies with condensed aminothiophenes: Microwave assisted cycloaddition reactions of thieno[3,4-d]-pyridazinone and thieno[3,4-c]quinolinone

The arylformazane (2) was produced via coupling the α-oxoarylhydrazones (1) with aromatic diazonium salts. These formazane condensed readily with ethyl cyanoacetate to yield arylazopyridazinones (4) that reacted with sulphur in the presence of piperidine
