In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 61070-98-2, name is Pyridazine-3,4-diamine, introducing its new discovery. category: pyridazine
Synthesis of 1-substituted [1,2,3]triazolo[4,5-d]pyridazines as precursors for novel tetraazapentalene derivatives
A series of 1-substituted 4,5-diformyl-[1,2,3]triazole derivatives were prepared by 1,3-dipolar cyclo-addition of aryl azides with acetylene dicarboxaldehyde mono-diethylacetal. The triazoles were readily converted into 1-substituted [1,2,3]triazolo[4,5-d]pyridazines in good yields. The 1-(2-nitrophenyl)-[1,2,3]triazolo[4,5-d]pyridazine was found to be a useful intermediate for the generation of the novel 5H-benzo[1,2,3]triazolo[1?,2?:1,2]triazolo[4,5-d]pyridazin-6-ium inner salt ring system.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 61070-98-2, and how the biochemistry of the body works.category: pyridazine
