Hcf2otf
Difluoromethyl triflate (TfO-CHF 2) 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). WebThen HCF2OTf (233 μL, 2.0 mmol, 4.0 eq) and DMF (10.0 mL) were added by syringes. The mixture was stirred at room temperature for 5 min and diaryliodonium salt (0.5 mmol, 1.0 eq) was added under N2. After stirring for 5 min, the reaction was quenched by H2O and the aqueous layer was extracted with Et2O. The combined organic layers were washed ...
