| Application: | 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. |
| General description: | Difluoromethyl triflate (HCF2OTf) is an easy to handle, air-stable and non-ozone-depleting liquid reagent for difluoromethylation. It can be prepared by reacting trifluoromethyltrimethyls |
