Electric Literature of 253-52-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 253-52-1, molcular formula is C8H6N2, introducing its new discovery.
Some Reactions of N-Alkoxycarbonyl Reissert Compounds with Heterocumulenes: Formation of the Imidazo<5,1-a>isoquinoline and Imidazo<5,1-a>phthalazine Systems and Related Chemistry
Chloroformate derived Reissert compounds of isoquinoline and of phenanthridine on treatment with base undergo cyclisation with isothiocyanates to give in good yields corresponding imidazo<5,1-a>isoquinoline and imidazo<1,5-f>phenanthroline derivatives.Phthalazine Reissert compound analogues give open chain adducts under the same conditions which can be cyclised to derivatives of the novel imidazo<5,1-a>phthalazine system by heating in the presence of molecular sieves.When carbon disulphide is the heterocumulene cyclisation is not observed but open chain dithio-ester derivatives can be isolated on alkylation of the intermediate sodium salts.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 253-52-1 is helpful to your research. Electric Literature of 253-52-1
