Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Trifluoromethanesulfonic anhydride can be used in the preparation of azido sugars such as 6-azido fucose. It can also be used as a promoter for the Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the absence of catalyst.Tf2O in combination with:Diphenyl sulfoxide, forms an efficient promoter system for the activation of thioglycosides for glycosylation reactions.2-chloropyridine, can be used for secondary amide activation.Potassium iodide, can effectively mediate the deoxygenation of sulfoxides to form sulfides.Hydrogen peroxide, for the selective oxidation of sulfanes to sulf-íoxides in the presence of oxidatively sensitive functional groups.Tf2O can react with:Ketones in the presence of a base to form vinyl triflates.Magnesium alkoxides to form corresponding symmetrical or unsymmetrical ethers.Sodium azide for the in situ preparation of triflyl azide.Electrophilic trifyl source.
