In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: Quinoxaline-2,3-diamine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 6640-47-7, name is Quinoxaline-2,3-diamine. In an article£¬Which mentioned a new discovery about 6640-47-7
Chemical and electrochemical reduction of pyrazino<2,3-b>quinoxalines
The hydrogenation of 2,3-dimethylpyrazino<2,3-b>quinoxaline 1 and 2-phenylpyrazino<2,3-b>quinoxaline 2 leads to the corresponding 5,10-dihydroderivatives 3b and 4b.LiAlH4 reduction of 2, of 2,3-dimethyl-6,7-diphenylpyrazino<2,3-b>pyrazine 8 and 2,6,7-triphenylpyrazino<2,3-b>pyrazine 9 furnishes the corresponding 1,2,3,4-tetrahydroderivatives 7, 10 and 11.NaBH4 reduction of 2 leads to a mixture of 4b and 7.In hydroorganic medium 1 and 2 are electrochemically reduced to 3b and 4b with which they form a redox system.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6640-47-7, help many people in the next few years.name: Quinoxaline-2,3-diamine
