4,5-Dihalo-3(2H)-pyridazinones have gained increasing importance in the synthetic chemistry of pyridazines over the last decade. In particular, new examples of nucleophilic displacement of halogens, novel types of N-protection leading to a more efficient functionalization, and the introduction of C-C coupling reactions by palladium catalysts illustrate the significant development in the field. All these aspects are covered by this review.
