Solvent-free methods are especially adapted to organic synthesis under Green Chemistry conditions. When coupled to microwave (MW) irradiation, it results in very efficient and clean procedures with noticeable improvements over classical methods. To take advantage of MW specific effects, the most suitable cases involve reactions with polar mechanisms with increase of the polarity during the progress of the reaction and late transition states along the reaction coordinates. Striking examples are described therein. To cite this article: A. Loupy, C. R. Chimie 7 (2004).

Les techniques de réactions sans solvant sont particulièrement adaptées aux conditions de la chimie verte. Quand elles sont couplées à l'irradiation par les micro-ondes, il en résulte des procédés efficaces et propres, avec de notables améliorations par rapport aux méthodes classiques. Pour tirer le meilleur profit des effets spécifiques des micro-ondes, il convient de considérer des réactions mettant en jeu des mécanismes polaires où la polarité augmente avec l'avancement de la réaction et des états de transition tardifs sur les coordonnées réactionnelles. Des exemples caractéristiques sont décrits ici. Pour citer cet article: A. Loupy, C. R. Chimie 7 (2004).
