Recyclable Organotungsten Lewis Acid and Microwave-Assisted Diels—Alder
in Water and in Ionic Liquids. — A novel methodology for Diels—Alder
14- 034 Reactions
reactions involves the use of water-soluble tungsten complex (I) as catalyst, microwave
irradiation, and ionic liquid [bmim]PF6 as solvent. Water can be also used as solvent,
but the ionic liquid facilitates the catalyst recycling. High reaction rates and chemoselectivity are achieved by the new method. — (CHEN, I.--.; YOUNG, J.-N.; YU*, S. J.;
