Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
Ms 2 O may be prepared by the dehydration of methanesulfonic acid with phosphorus pentoxide. [2] P 2 O 5 + 6 CH 3 SO 3 H → 3 (CH 3 SO 2) 2 O + 2 H 3 PO 4. Ms 2 O can be purified by distillation under vacuum (distillation of a solid) or by recrystallization from Methyl tert-butyl ether/toluene.
Methanesulfonic acid (MsOH, MSA) or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH 3 SO 3 H and structure H 3 C−S(=O) 2 −OH. It is the simplest of the alkylsulfonic acids ( R−S(=O) 2 −OH ).
Methanesulfonyl chloride (mesyl chloride) is an organosulfur compound with the formula CH 3 SO 2 Cl. Using the organic pseudoelement symbol Ms for the methanesulfonyl (or mesyl) group CH 3 SO 2 –, it is frequently abbreviated MsCl in reaction schemes or equations. It is a colourless liquid that dissolves in polar organic solvents but is ...
Triflic anhydride is prepared by dehydration of triflic acid using P 4 O 10. [2] Triflic anhydride is useful for converting ketones into enol triflates. [4] In a representative application, is used to convert an imine into a NTf group. [5] It will convert phenols into a triflic ester, which enables cleavage of the C-O bond. [6] [7]
Triflidic acid (IUPAC name: tris[(trifluoromethyl)sulfonyl]methane, abbreviated formula: Tf 3 CH) is an organic superacid. It is one of the strongest known carbon acids and is among the strongest Brønsted acids in general, with an acidity exceeded only by the carborane acids .
In organic chemistry, triflate (systematic name: trifluoromethanesulfonate), is a functional group with the formula R−OSO 2 CF 3 and structure R−O−S(=O) 2 −CF 3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO 2 CF 3. For example, n-butyl triflate can be written as CH 3 CH 2 CH ...
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.
