一般說明

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。

應用

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

Friedel–Crafts Acylation

The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form monoacylated products.
