在胶束体系中，三氟甲磺酸钪（Sc（OTf）（3））催化烯醇醚与醛的羟醛缩合反应得到了成功的结果。虽然反应在水中缓慢进行，但在少量表面活性剂的存在下观察到反应性的显著增强。在这些系统中，多功能的碳-碳键形成反应在水中进行，而不使用任何有机溶剂。(C)1997年爱思唯尔科学有限公司
Scandium triflate (Sc(OTf)(3))-catalyzed aldol reactions of silyl enol ethers with aldehydes were successfully carried out in micellar systems. While the reactions proceeded sluggishly in water, remarkable enhancement of the reactivity was observed in the presence of a small amount of a surfactant. In these systems, versatile carbon-carbon bond-forming reactions proceeded in water without using any organic solvents. (C) 1997 Elsevier Science Ltd.
