Two previously unknown thienopyridopyridazine ring systems, thieno[2′,3′:5,6]pyrido[2,3‐ d ]pyridazine‐5,8,9(4 H ,6 H ,7 H )‐trione ( 4 ) and thieno[3′,2′:5,6]pyrido[2,3‐ d ]pyridazine‐4,5,8(6 H ,7 H ,9 H )‐trione ( 10 ) were synthesized and their chlorination reactions with phosphorus oxychloride were investigated.
