In title cycloadditions microwave irradiation improves product yields and reduces dramatically reaction times in comparison with classical heating with and without refluxing solvents. In the double cycloaddition of nitrile oxides to anthracene a selectivity in favour of unsymmetrical bis-cycloadduct is observed.

Abstract
In title cycloadditions microwave irradiation improves product yields and reduces dramatically reaction times in comparison with classical heating with and without refluxing solvents. In the double cycloaddition of nitrile oxides to anthracene a selectivity in favour of unsymmetrical bis-cycloadduct is observed.File in questo prodotto:
