Abstract

Direct functionalization of 4,5‐dichloropyridazin‐6‐one with some nucleophiles in seven solvents gave regioselectively 5‐halo‐4‐substituted‐pyridazin‐6‐ones as main product. Reaction of 4,5‐dichloropyridazin‐6‐one with 2‐mercaptopyrimidine (2 equivalents) also afforded 4,5‐di(pyrimidin‐2‐ylsulfanyl)pyridazin‐6‐one as the main product.
