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 Article£¬once mentioned of 932-22-9
Studies of Pyridazine Compounds. XXVI. The Synthesis of Pyridazino<4,5-b>pyrrolo<1,2-d><1,4>oxazines and a Pyridazino<4,5-b>pyrrolo<1,2-d>thiazine
The tricyclic oxazines 3 and 5 were obtained by ring closure of (2-hydroxymethyl-1-pyrrolidinyl)-3(2H)-pyridazinones 2d,e,g, respectively, prepared from 4,5-dichloro-3(2H)-pyridazinones with L-prolinol.The synthesis of the thiazine analogue 4a was achieved by treatment of 2d with thionyl chloride and the subsequent reaction with sodium sulfide.The structures of the compounds were supported by spectroscopic evidence.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 932-22-9, and how the biochemistry of the body works.Electric Literature of 932-22-9
