New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.COA of Formula: C8H4Cl2N2, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
2,3-Dimercaptoquinoxaline 1 was allowed to react with some dihalo compounds and chloroanil using PTC technique to afford the corresponding polyfused quinoxalines 2a-d. The reaction of compound 1 with different monohalo compounds under the same PTC conditions or in refluxing ethanol in presence of piperidine catalyst gave (1,4)dithiino-, thieno-, (1,4)thiazino-, and pyrroloquinoxalines 3a-5b. The addition of compound 1 to alpha,beta-unsaturated nitriles was investigated to give the corresponding (1,5)dithiapinoquinoxalines 6a-7b and thiapinoquinoxalines 8a,b. The treatment of compound 1 with active nitriles furnished the corresponding thienoquinoxalines 9a-c and pyridazinoquinoxaline 10.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C8H4Cl2N2, you can also check out more blogs about2213-63-0
