Its pK 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 pK a value of 2,4,6-trinitrophenol (picric acid), anchored to zero to crudely approximate the aqueous pK a scale [2]), making it more acidic than triflic acid (pK a MeCN = 0.70, pK a DCE ...
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. The triflyl group is often represented by –Tf. The related triflate group (trifluoromethanesulfonate) has the formula R−OSO 2 CF 3, and is represented by –OTf. [1]
The trifluoromethyl group is a functional group that has the formula-CF 3. The naming of is group is derived from the methyl group (which has the formula -CH 3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H– CF 3, 1,1,1-trifluoroethane H 3 C – CF 3, and hexafluoroacetone F 3 C –CO– CF 3.
It is commonly used as Li-ion source in electrolytes for Li-ion batteries as a safer alternative to commonly used lithium hexafluorophosphate. [3] It is made up of one Li cation and a bistriflimide anion.
Ditolylguanidine is a sigma receptor agonist. [1] It is somewhat [2] selective for sigma receptors, but non-selective between the two sigma receptor subtypes, binding to both σ1 and σ2 with equal affinity. [3] It has neuroprotective [4] and antidepressant effects, [5] and potentiates the effects of NMDA antagonists. [6]

Sulfonyl groups can be written as having the general formula R−S(=O) 2 −R′, where there are two double bonds between the sulfur and oxygen. [1]: 53 [2] Sulfonyl groups can be reduced to the sulfide with diisobutylaluminium hydride (DIBALH). Lithium aluminium hydride (LiAlH 4) reduces some but not all sulfones to sulfides. [1]: 1851
