Dangerous Goods

CAS number:252976-51-5    molecular formula:C3F9O9S3Yb.xH2O

overview

compound introduction

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。 用途: 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。
