Metalation of diazines XVII Very hindered bases as new metalating agents, Improvement of regioselectivity for the metalation of 3-chloro-6-methoxypyridazine
The different factors governing the regioselectivity of the metalation of 3-chloro-6-methoxypyridazine with alkylamides were studied. Very hindered bases were used as new metalating agents and a very good regioselectivity was obtained.
