Application of 41933-33-9, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 41933-33-9, Name is 2-Benzyl-4,5-dichloropyridazin-3(2H)-one, molecular formula is C11H8Cl2N2O. In a Article，once mentioned of 41933-33-9
Ring contraction of 7-substituted 2-phenyl-4H-pyridazino<4,5-e><1,3,4>thiadiazin-8(7H)-ones (5a-d) to 5-substituted 3-phenyl-1H-pyrazolo<3,4-d>pyridazin-4(5H)-ones (7a-d), through base-induced extrusion of sulphur, is described.Similar reactions proceed, not only on the 4-acetyl derivatives (4a-d) in basic media, but on 5a and the 4-methyl derivative (6a) thermally.Probable mechanism of these reactions are discussed.A comparable approach to the ring contraction, photochemical cyclisation of 2-substituted 5-(1-alkyl-2-benzylidenehydrazino)-4-chloro-3(2H)-pyridazinones (9a-e) to the corresponding 1-alkylpyrazolo<3,4-d>-pyridazinone derivatives (8a-e) is also performed.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 41933-33-9. In my other articles, you can also check out more blogs about 41933-33-9
