DIRECT AMINATION OF 3(2H)-PYRIDAZINONES: RE-INVESTIGATION OF THE REACTION OF 3,6-DIMETHOXYPYRIDAZINE WITH HYDRAZINE
3,6-Dimethoxypyridazine has been shown to react with hydrazine via 4-amination of 6- methoxy and 6-hydrazino-3(2H)-pyridazinones to give 4-amino-6-methoxy- and 4-amino-6-hydrazino-3(2H)-pyridazinones, and not the corresponding 5-amino isomers as previously reported.The published synthesis of the 5-amino isomers, used to confirm the earlier findings, is incorrect as regards 5-amino-6-hydrazino-3(2H)-pyridazinone, which has been prepared by an alternative route.The 4-aminnation reaction has been extended to 6-chloro-3(2H)-pyridazinone.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 19064-67-6
