New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Recommanded Product: 2213-63-0, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
Condensation of 4-amino-5-mercapto-3-(m-chlorophenyl)-s-triazole 1 with cyanogen bromide gives 6-amino-3-(m-chlorophenyl)-s-triazolo [3,4-6]-1,3,4-thiadiazole 2 which on condensation with chloranil yields 3,9-di-(m-chlorophenyl)-6,14-dioxo-bis-(s-triazolo [3,4-b]-1,3,4-thiadiazolo [3,2-b] [imidazo [4,5-b] cyclohexane]-5a, 6a-diene) 3. 3-(m-Chlorophenyl)-s- triazolo [3,4-b]-1,3,4-thiadiazolo [3,2-b] imidazo [4,5-b] quinoxaline 4 is obtained by a similar condensation of 2 with 2,3-dichloroquinoxaline. The reaction of 2 with alpha-haloketones followed by bromination affords 7-aryl-3-(mchlorophenyl)-imidazo [2,1-b]-1,3,4-thiadiazolo [2,3-c]-s-triazoles 5 and their 6-bromo analogues 6 respectively. The antibacterial and antifungal activities of some of the compounds have also been evaluated.
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 2213-63-0, help many people in the next few years.Recommanded Product: 2213-63-0
