Electric Literature of 932-22-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.932-22-9, Name is 4,5-Dichloro-3(2H)-pyridazinone, molecular formula is C4H2Cl2N2O. In a Patent£¬once mentioned of 932-22-9
A pyridazinone compounds and its synthetic method (by machine translation)
The invention relates to a pyridazinone compounds and its synthetic method, said compound of the general formula as follows: Wherein R1 As the C1 – C4 alkyl or halogen; R2 As the C1 – C4 alkyl or halogen; R3 Straight chain aliphatic amine or cyclic amine or c mercapto or aromatic methoxy; R4 Is halogen or c mercapto; at the time of preparation, first halo acetyl halogen reaction with benzene process fu – grams of synthetic alpha – halogenated acetophenone, with 4, 5 – dichloro – 3 (2 H) – pyridazinone substitution reaction synthetic intermediates, the generated intermediate under the catalysis of the alkaline reagent, with nucleophiles such as amines or cyclic aliphatic amine or propanethiol undergo the substitution reaction synthesis pyridazinone compounds. Compared with the prior art, the present invention the entire process is simple, and good repeatability, and is simple, wide range of application, it has very good application prospect.
