Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C4H2Cl2N2O. Introducing a new discovery about 932-22-9, Name is 4,5-Dichloro-3(2H)-pyridazinone
Synthesis of analogues of the 2,3,6-triazaphenothiazine ring system
Treatment of 2,3-dichloroquinoxalines with 2-amino-6-picoline-3-thiol gave a mixture of 2,3-bis(2-amino-6-picolinyl-3-thio)quinoxalines (16, R = H, Cl) and 2,3-bis (N,N-dimethylamino)quinoxalines (15, R = H, Cl) separated by fractional crystallization. A similar reaction of 3-amino-6-methoxypyridine-2(1H)-thione (9) with 4,5-dichloropyridazin-3(2H)-one (21) gave 4-chloro-5-(3-amino-6-methoxypyridyl-2-thio)pyridazin-3(2H)-one (22). Concentrated hydrochloric acid-catalysed cyclization of 22 gave the nonrearranged 7-methoxy-2,3,6-triazaphenothiazin-1(2H)-one. The action of compound 22 in refluxing glacial acetic acid gave, on the other hand, 7-methoxy-2,3,6-triazaphenothiazin-4(3H)-one via a Smiles rearrangement. These cyclized compounds are the first known derivatives of the new 2,3,6-triazaphenothiazine ring system.
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: C4H2Cl2N2O, you can also check out more blogs about932-22-9
