Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 78593-33-6, 78593-33-6,introducing its new discovery.

Using the same procedure as that described above but from 3-bromocinnoline there was obtained 3-(4-methoxyphenylthio)cinnoline Yield: 74.6% M.P.: 108 C. (isopropanol)

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 78593-33-6 is helpful to your research. 78593-33-6

78593-33-6. Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media. Which mentioned a new discovery about 78593-33-6.

(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50 ml of dimethylsulphoxide was stirred and heated at 120 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained. Yield: 10.2%

Starting material 1-A (11.8 g, 40 mmol), starting material 1-B (16.7 g, 80 mmol), CuI (3.8 g, 20 mmol), potassium carbonate (11.1 g, 80 mmol), and 1-methyl-1H-imidazole (3.3 g, 40 mmol) were added to 250 ml of toluene, and then, the mixture was refluxed while stirring under a nitrogen atmosphere for 7 days. Then, the reaction mixture was cooled to room temperature, 300 ml of water was added to isolate the organic layer, and the water layer was extracted twice with 250 ml of dichloromethane. The extracted organic layer was stirred with MgSO4 to remove water therefrom, and the organic layer was filtered and evaporated under reduced pressure. The resulting solid was subjected to column chromatography using, as an eluent, dichloromethane and normal hexane to obtain 5.6 g of Intermediate 1-C at the yield of 33%.
