Trifluoromethanesulfonic acid difluoromethyl ester Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Difluoromethyl triflate (TfO-CHF2) can be used as a reagent:- In difluoromethylation reaction.
- To prepare difluoromethoxylated heterocycles by reacting with hydroxylated N-based heterocycles.
- To synthesize trifluoromethylated arenes by treating with diaryliodonium salts in the presence of copper and tetrabutylammonium difluorotriphenylsilicate (TBAT).
It allows for a simple method toward the preparation of difluoromethyl ethers and thioethers under basic conditions from alcohols and thiols. Difluoromethyl phenols can also be obtained in a single pot from boronic acids and C-H activation of arenes.
Allgemeine Beschreibung
Difluoromethyl triflate (HCF2OTf) is an easy to handle, air-stable and non-ozone-depleting liquid reagent for difluoromethylation. It can be prepared by reacting trifluoromethyltrimethylsilane (TMSCF3) and triflic acid in the presence of titanium tetrachloride (TiCl4).Trifluoromethanesulfonic acid difluoromethyl ester Upstream-Materialien And Downstream Produkte
