General description
三氟乙酸（TFA）是一种有机氟化合物，在有机合成中用作各种酸催化反应的试剂，如环氧化合物开环、仿生环化、Cope 重排和天然产物合成。由于 TFA 的高挥发性、在有机溶剂中的溶解度和酸性强度，其物理化学特性比其他酸更有优势。当 TFA 用作试剂时，由于极高的挥发性，可以轻松通过蒸发分离产物。挥发性较低的酸，如硫酸或对甲苯磺酸，可能需要中和或萃取处理。

Homosubstituted amido-functionalized polyoctahedral oligomeric silsesquioxanes (POSS) have been synthesized by using acyl chlorides in high yields (ca. 95%). The method proved to be superior over "conventional" syntheses applying carboxylic acids or acid anhydrides, which are much less efficient (ca. 60%

Fully substituted glucomannan triacetate (GMTAc) (degree of substitution (DS)=3.0) was prepared from konjac glucomannan (KGM) treated with acetic acid and trifluoroacetic anhydride (TFAA). The peaks in the (1)H- and (13)C NMR spectra of GMTAc were assigned in detail based on

Transradial access for cardiac catheterisation results in lower bleeding and vascular complications than the traditional transfemoral access route. However, the increased radiation exposure potentially associated with transradial access is a possible drawback of this method. Whether transradial access is associated
