Rh(II) salt and a Lewisacid, Sc(OTf)3, as a highly active and robust cooperative catalyst system for ketone hydroacylation was developed. The catalyst system showed highturnovernumbers (up to ca. 400) even under air, whereas the corresponding Rh(I)/Sc(OTf)3 system did not work well. The application of the Rh(II)/Sc system was also extended to hydroacylation of olefins and an enantioselective reaction
