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.
For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding triflate anion, CF 3 SO − 3, is an extremely stable polyatomic ion; this comes from the fact that triflic acid (CF 3 SO 3 H) is a superacid; i.e. it is more acidic than pure sulfuric acid, already one of the strongest acids known.
Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.
Preparation of the trifluoromethyltrimethylsilane was reported by Ingo Ruppert in 1984. [11] In 1989, Prakash and Olah first reported activation of TMSCF 3 by fluoride to perform nucleophilic trifluoromethylation of carbonyl compounds. [12]
The FDA determined that the data presented in a 2022 color additive petition show that this ingredient causes cancer in male laboratory rats exposed to high levels of FD&C Red No. 3 because of a ...
Bis(trifluoromethanesulfonyl)aniline is a source of the triflyl (CF 3 SO + 2) group. The disulfonimides are of the type R−S(=O) 2 −N(H)−S(=O) 2 −R' with two sulfonyl groups flanking an amine. [10] As with sulfinamides, this class of compounds is used as catalysts in enantioselective synthesis. [10] [11] [12]
Investigators Rarely Sustain Allegations Of Any Kind. Sources: Invisible Institute, City of Chicago, Census Bureau, CNN Of 10,500 complaints filed by black people between 2011 and 2015, just 166 — or 1.6 percent — were sustained or led to discipline after an internal investigation.
