Abstract
The coupling of graphite (as a support) with microwaves (as an energy source), a new type of « dry reaction », was studied for some Diels-Alder and Hetero-Diels-Alder reactions. It was also possible to achieve in a few minutes, at atmospheric pressure and without solvent, retro-Diels-Alder reactions. All these synthesis have been realized in very short times, without any thermal decomposition products and even in presence of volatile reagents.
