Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. HPLC of Formula: C9H8N2. Introducing a new discovery about 6344-72-5, Name is 6-Methylquinoxaline
The Thermolysis of Polyazapentadienes. Part 2. Formation of Quinoxalines from 5-Aryl-1-phenyl-1,2,5-triazapentadienes
Thermolysis in the gas phase of 5-(p-substituted phenyl)-1-phenyl-1,2,5-triazapentadienes at 600 deg C and 10-2 Torr gives 6-substituted quinoxalines.The yield is ca. 30 percent, and is independent of the electronic nature of the substituent.The corresponding 5-(o-substituted) derivatives give 5-substituted quinoxalines, though the yield is lower, and quinoxaline itself is a major contaminant, due to ipso attack and ejection of the substituent. 5-(m-Substituted) derivatives give mixtures of 5- and 6-substituted quinoxalines on pyrolysis.The 5-isomer is dominant for compounds with m-alkyl substituents, while the 6-isomer is the major product for those with electron-withdrawing or electron-donating m-substituents.
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.HPLC of Formula: C9H8N2, you can also check out more blogs about6344-72-5
