Rh(II) salt and a Lewis acid, Sc(OTf)3, as a highly active and robust cooperative catalyst system for ketone hydroacylation was developed. The catalyst system showed high turnover numbers (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
开发了 Rh(II) 盐和路易斯酸 Sc(OTf)3 的组合,作为用于酮加氢酰化的高活性和稳健的协同催化剂体系。即使在空气中,催化剂体系也显示出高周转数(高达约 400),而相应的 Rh(I)/Sc(OTf)3 体系效果不佳。Rh(II)/Sc 体系的应用还扩展到烯烃的加氢酰化和对映选择性反应。
