Abstract
Scandium(III) perfluorooctanesulfonate [scandium(III) perflate, Sc(OPf )(3)] was prepared from either scandium(III) chloride or oxide and per fluorooctanesulfonic acid. The perflate thus obtained acts as a novel Lewis acid catalyst for the intermolecular hetero Diels-Alder reaction of aldehydes with non-activated dienes under mild conditions. The cha racteristic features of the catalyst include (i) low hygroscopicity, ( ii) ease of handling, and (iii) robustness for the recycling use.
