Abstract

Scandium (III) perfluorooctanesulfonate [scandium (III) perflate, Sc (OPf) 3] was prepared from either scandium (III) chloride or oxide and perfluorooctanesulfonic 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 characteristic features of the catalyst include (i) low hygroscopicity,(ii) ease of handling, and (iii) ...
