S. Dima et al., 1,3 dipolar cyclondition of 1-methylphtalazinium ylides upon asymmetric olefins in solid phase under microwaves, REV RO CHIM, 45(6), 2000, pp. 555-560
We report here a comparative study of reactivity of 1-methyl-phthalazinium
ylides with ethyl-acrylate and acrylonitrile under microwave irradiation us
ing solid media conditions. The reagents were either impregnated on a solid
mineral support in the absence of solvent. The reactivity of 1-methylphtha
lazinium ylides is greather than that found under classical conditions.
