The reagent was used in trifluoromethylation of a thiophenolate. S-(trifluoromethyl)dibenzothiophenium tetrafluoroborate is a commercially available and known trifluoromethylation reagent based on the same principle first documented in 1990. [64] [65] In this type of compound sulfur has been replaced by oxygen, selenium and tellurium.
Sulfoxaflor is used as a systemic insecticide. Trifluralin, as with several dinitritroaniline herbicides, is a trifluoromethyl herbicide. Fluazifop is another, a phenoxy herbicide. The trifluoromethyl group can also be added to change the solubility of molecules containing other groups of interest.
It is unclear why trifluralin's exotic 4-trifluoromethyl was tested so early (1960), before more common candidates such as fluoro, bromo, or iodo. [7] By 1968, trifluralin was internationally available, including Australia and New Zealand, [6] and trifluralin was the 5th most used herbicide in the US, at 22,960,000 pounds (10,410 t) by 1974.

Many organofluorine compounds are generated from reagents that deliver perfluoroalkyl and perfluoroaryl groups. (Trifluoromethyl)trimethylsilane, CF 3 Si(CH 3) 3, is used as a source of the trifluoromethyl group, for example. [24] Among the available fluorinated building blocks are CF 3 X (X = Br, I), C 6 F 5 Br, and C 3 F 7 I.
Fluridone's main action to disrupt photosynthesis in plants is by preventing the secretion of abscisic acid. [8] As higher eukaryotes, such as humans, also rely on an abscisic acid pathway [9] to create inflammation in normal physiological processes, fluridone could be investigated as being of interest in the development of anti-inflammatory agents.
Trifluoromethylsulfur pentafluoride, CF 3 SF 5, is a rarely used industrial greenhouse gas. [1] It was first identified in the atmosphere in 2000. [2] Trifluoromethylsulfur pentafluoride is considered to be one of the several "super-greenhouse gases".
A label is a legally binding document that mandates how the pesticide can and must be used and failure to follow the label as written when using the pesticide is a federal offence. [16] [17] Fomesafen is normally applied postemergence (when weeds are visible in the crop) but may also be used preemergence.
An additional stabilization is achieved by the trifluoromethyl group, which acts as a strong electron-withdrawing group using the sulfur atom as a bridge. Triflates have also been applied as ligands for group 11 and 13 metals along with lanthanides. Lithium triflates are used in some lithium ion batteries as a component of the electrolyte.
