1,3-Dipolar cycloaddition of 2-diazopropane to 2-methyl-6-phenylpyridazin- 3(2H)-one. The formation of pyrazolo/3,4-D/pyridazine derivatives

In a regiospecific 1,3-dipolar cycloaddition of 2- diazopropane to 2-itiethyl-6-phenylpyridazin-3(2H)-one the primary cycloadduct and rearranged NH,NH- dihydro cycloadduct were isolated. They were transformed, dependent on the reaction conditions into 1,2
