overview

compound introduction

三氟甲磺酸是最强的单质子有机酸。它是通过双(三氟甲硫基)汞与过氧化氢水溶液的氧化反应进行合成的。它在二甲亚砜、二甲基乙酰胺和二甲基甲酰胺等碱性溶剂中完全解离。已通过电导法研究了其在非水溶剂中的解离。通过混合三氟甲磺酸与HNO3, 可形成三氟甲烷磺酸硝鎓,这是一种出色的硝化试剂。 应用 三氟甲磺酸可用作苯乙烯、六甲基环三硅氧烷和 L,L-丙交酯的阳离子聚合的引发剂; 三氟甲磺酸是一种通用试剂,可用作以下研究的催化剂: 芳香族化合物与苯甲酸甲酯的Friedel-Crafts酰化反应;二烷基二硫化物与末端炔烃的加成反应;合成含有三氟甲磺酸丙基铵和甲基侧链基团的单环四硅氧烷 (Am-CyTS);制备用于合成氟化2,5-取代的1-乙基-1H-苯并咪唑衍生物的起始试剂;三氟甲磺酸芳基酯的合成、链烯酸的内酯化和 E-烯烃的形成 去糖基化剂 Trifluoromethanesulfonic acid, or triflic acid, is one of the strongest monoprotic acids available. It can be used as a precursor and a catalyst in organic chemistry. It is useful in the deglycosylation of glycoproteins. A versatile reagent employed in the synthesis of aryl triflates, the lactonization of alkenoic acids, and the formation of E-alkenes. Deglycosylation agent
