Regioselective desymmetrization of 4-substituted pyridazin-3,6-diones using sterically hindered 2,4,6-triisopropylphenyl -sulfonylchloride allowed efficient sequential palladium cross-coupling reactions. ... The commercially available 3,6-dichloropyridazine 4a (R = H) has been already used for that purpose. 8, 9, ...
