Related Products of 288-14-2, 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, 288-14-2, molcular formula is C3H3NO, introducing its new discovery.
A series of heterocylic compounds was synthesized from 1-(3,4-dimethoxyphenyl)-3-(4-ethoxyphenyl)prop-2-en-1-one 1, which was reacted with thiourea, ethyl acetoacetate, p-nitro-phenylhydrazine and hydroxylamine hydrochloride afforded thioxopyrimidine 2, tetrahydro-terphenyl 3, 1,3,5-triarylpyrazole 4, and 3,5-diarylisoxazole 5 derivatives, respectively. While, upon reaction of thioxopyrimidine 2 with piperidine, anthranilic acid or hydrazine hydrate afforded piperidin-1-yl-1,4-dihydropyrimidine 6, pyrimido[2,1-b]quinazoline 7 and 2-hydrazinyl-1,4-dihydropyrimidine 8 derivatives, respectively. Finally, the latter compound 8 was heterocyclized with formic acid, acetic anhydride, carbon disulfide, acetyl acetone or phthalic anhydride resulting the corresponding triazolo[4,3-a]pyrimidines 9, 10, 11, pyrazolyl pyrimidine 12 and imide derivatives 13, respectively. The structural assignments of new compounds were based on their elemental analysis and spectral (IR1H NMR and13C NMR) data. All the newly substituted pyrimidine, isoxazole, pyrazole and fused triazolopyrimidine derivatives displaying potential analgesic and anti-convulsant activities.
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 288-14-2 is helpful to your research. Related Products of 288-14-2
