Synthesis with Nitriles: Synthesis of Some New Mercaptopyridazine, Mercaptopyridazino[1,6-a]quinazoline and Thiophene Derivatives

2-(1-(4-Bromophenyl)-2-thiocyanatoethylidene)malononitrile (3) undergoes azo coupling with diazotized aromatic amines to afford arylhydrazone derivatives, which are readily cyclized to afford the corresponding 3(2H)-pyridazinimine derivatives upon reflux in aqueous NaOH. Under similar condition an o...
