3,6-Difluoropyridazine (cas: 33097-39-1) belongs to pyridazine derivatives. Pyridazine-based compounds continued to be a great source of biologically active compounds as evidenced by the number of publications which emerged in 2021. In the past decade, X-ray data were reported with regard to the characterization and structural elucidation of a number of pyridazine-metal complexes, including pyridazine ligands with zinc, nickel, copper, cadmium and ruthenium.Reference of 33097-39-1

The proton sponge-triethylamine tris(hydrogen fluoride) system as a selective nucleophilic fluorinating reagent for chlorodiazines was written by Darabantu, M.;Lequeux, T.;Pommelet, J.-C.;Ple, N.;Turck, A.;Toupet, L.. And the article was included in Tetrahedron Letters in 2000.Reference of 33097-39-1 This article mentions the following:

The proton sponge-triethylamine tris(hydrogen fluoride) mixture provides a mild and efficient fluorinating reagent for the selective introduction of a fluorine atom, by halogen exchange, into dichlorodiazines. In the experiment, the researchers used many compounds, for example, 3,6-Difluoropyridazine (cas: 33097-39-1Reference of 33097-39-1).
