concerning synthesis, structure and biological activity of some new pyridazinederivatives. Syntheses have been done both under classical conditions and microwave [in liquid phase and interphasic transfer catalysis (PTC)]. The MW induced a remarkable acceleration for the [3+2] dipolar cycloaddition reaction of pyridazinium ylides to activated alkenes and alkynes, the yields were increased in some cases
