Bis(trifluoromethanesulfonyl)aniline is the organic compound with the formula C 6 H 5 N(SO 2 CF 3) 2. [1] It is a white solid. The compound is used to install the triflyl group (SO 2 CF 3). Its behavior is akin to that of triflic anhydride, but milder.
Triflyl group. In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula R−SO 2 CF 3 and structure R−S(=O) 2 −CF 3.
[1] Its p K a value in water cannot be accurately determined but in acetonitrile it has been estimated as −0.10 and in 1,2-dichloroethane −12.3 (relative to the p K a value of 2,4,6-trinitrophenol ( picric acid ), anchored to zero to crudely approximate the aqueous p K a scale [ 2 ] ), making it more acidic than triflic acid (p K a MeCN = 0 ...
[35] [36] The first copper catalysed coupling was reported in 2009 and based on an iodoarene, a trifluoromethylsilane, copper iodide and 1,10-phenanthroline. [37] Variations include another CF 3 donor potassium (trifluoromethyl)trimethoxyborate , [ 38 ] the use of aryl boronic acids [ 39 ] [ 40 ] or the use of a trifluoromethyl sulfonium salt ...
In a mouse study, researchers found that zolpidem (Ambien), a common sleep aid, could prevent the brain from effectively clearing up 'waste', though it remains unclear whether this could affect ...

Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups. It is sometimes referred to as Kobayashi's anion in honour of Hiroshi Kobayashi who led the team that first synthesised it. [1]
