一般描述
已经通过原子力显微镜（AFM）研究了4-氨基苯硫酚和三氟甲磺酸镱(III)水合物膜的逐层组装。 据报道，双(恶唑啉基)-吡啶- 钪(III) 三氟甲磺酸盐络合物能够催化各种吲哚的对映选择性Friedel-Crafts加成反应。
应用
三氟甲磺酸镱(III)水合物（Yb(OTf)3）已被用作Lewis酸催化剂，用于以下研究：
- 通过Biginelli环缩合反应，合成二氢嘧啶（DHPM）衍生物monastrol。
- 酮与醛的交叉醛醇反应。
- 合成β-酮烯醇醚。
- 在新型立体选择性分子内Diels-Alder反应中，合成deoxypenostatin A。

The enantioselective Friedel-Crafts addition of a variety of indoles catalyzed by bis(oxazolinyl)pyridine-scandium(III) triflate complexes (Sc(III)-pybox) was accomplished utilizing a series of beta-substituted alpha,beta-unsaturated phosphonates and alpha,beta-unsaturated 2-acyl imidazoles. The acyl phosphonate products were efficiently transformed into esters and amides, whereas
