Commercially available anilines were converted by a two step, one-pot process to the corresponding pyridazinones in good to excellent yields. During the process research, a significant halogen exchange was confirmed and prevented which allowed the process to be scaled to multikilogram quantities.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: pyridazine, you can also check out more blogs about1698-53-9

5788-58-9, Name is 4,5-Dibromopyridazin-3(2H)-one, belongs to pyridazine compound, is a common compound. name: 4,5-Dibromopyridazin-3(2H)-oneIn an article, once mentioned the new application about 5788-58-9.

Six novel photochromic bisarylpyridazinones containing 2,5-dimethylthiophene or 5-methyl-2-phenylthiazole unit were synthesized, and their photochromic and fluorescence properties were investigated. The bisarylpyridazinones underwent reversible color change upon irradiation with UV or visible light. The effect of solvents on the absorption spectra of the bisarylpyridazinones was investigated. The closed-ring forms of bisarylpyridazinones displayed negative solvatochromism which was attributed to the high dipolar characters of the molecule. The open-ring forms of bisarylpyridazinones showed fluorescence at 400-480 nm upon excitation at 302 nm, and the intensities of emission bands gradually decreased during the ring-closing photoreactions. Among the synthesized bisarylpyridazinones, 4,5-bis(5-methyl-2-phenylthiazol-4-yl)-2-methyl(or 2-phenyl) pyridazin-3(2H)-ones (5O and 6O) displayed rather large absorption and emission spectral change, higher quantum efficiency during the photoreaction compared to others. A high conversion ratio (94%) to the closed form was observed for 5O.
