1,3-Dipolar Cycloaddition of Pyridazinium Ylides with Perhalocycloalkenes and Thermal Decomposition of the Adducts

Some pyridazinium N-ylides underwent 1,3-dipolar cycloaddition with perhalocyclopropenes and with a perhalocyclobutene.Thermal decomposition and chemical transformations of the pyrolyzed products afforded various hitherto unknown 2-chloropyrazolopyridazine derivatives.Keywords - pyridazinium N-ylide; pyridazine N-acylimine; N-acyliminopyridazine; 1,3-dipolar cycyloaddition; thermal ring-opening; diazaindolizine; pyrazolopyridazine; 2-chloropyrazolopyridazine.
