Synthesis of some 3,6‐disubstituted pyridazines

Abstract Some novel 3‐halo‐6‐(4‐substituted‐phenoxy)pyridazines and 3,6‐di‐(4‐substituted‐phenoxy)pyridazines were synthesized from 3,6‐dichloropyridazine or 3,6‐diiodopyridazine. 3,6‐Diiodopyridazine was prepared from 3,6‐dichloropyridazine using hydriodic acid/iodine monochloride.
