摘要：

Difluorotris(pentafluoroethyl)phosphorane, (C2F5)(3)PF2, was found to catalyze Diels-Alder reactions of alpha,beta-unsaturated ketones or aldehydes with conjugated dienes or cyclodienes providing the cycloaddition products in high yields. Only a small quantity of this catalyst is required to complete the Diels-Alder reaction. The developed protocol is more convenient than the procedures reported in the literature. Several cyclohexene, naphthalene and norbornene derivatives were obtained in moderate to good yields. (C) 2014 Elsevier B.V. All rights reserved.
