Electric Literature of 13099-95-1, 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, 13099-95-1, molcular formula is C11H10O4, introducing its new discovery.
Condensation of resorcinols (I) with (i) ethyl 2,3-dihydro-3-oxobenzofuran-2-carboxylate (II) and (ii) ethyl 2,3-dihydro-3-oxonaphtho<1,2-b>furan-2-carboxylate (VI) in the presence of phosphorus oxychloride gives the corresponding 2-alkyl-3-hydroxybenzofuro<2,3-c><1>benzopyran-6(H)-ones (III) and 2-alkyl-3-hydroxynaphtho<1,2-b>furo<2,3-c><1>benzopyran-6(H)-ones (VII) which on treatment with methylmagnesium iodide afford 2-alkyl-3-hydroxy-6,6-dimethyl-6H-benzofuro<2,3-c><1>benzopyrans (IV) and 2-alkyl-3-hydroxy-6,6-dimethyl-6H-naphtho<1,2-b>furo<2,3-c><1>benzopyrans (VIII) respectively.The pyrans (IV) are alkylated with 2-chloroethylpyrrolidine to give the corresponding basic ethers (V).
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 13099-95-1 is helpful to your research. Electric Literature of 13099-95-1
