Yield	Reaction Conditions	Operation in experiment
61%	With tert.-butylhydroperoxide; trifluoroacetic acid; In dichloromethane; water; for 16h;	General procedure: Difluoromethylation of Heterocycles Standard Procedures: Procedure B: To a solution of heterocycle (0.25 mmol, 1.0 equiv) and zinc difluoromethanesulfinate (DFMS) (173 mg, 0.50 mmol, 2.0 equiv ‘calculated as anhydrous’) in dichloromethane (1.0 mL) and water (0.4 rnL) at room temperature was added trifluoroacetic acid (20 μL, 0.25 rnmol, 1.0 equiv) followed by slow addition of tert-butyl hydroperoxide (70% solution in water, 0.1 mL, 0.75 mmol, 3.0 equiv) with vigorous stirring. The reaction was monitored by thin layer chromatography until completion. For substrates which do not go to completion in 24 hours, a second addition of DFMS (2.0 equiv) and tert-butyl hydroperoxide (3.0 equiv) may be added to drive the reaction further. Upon consumption of starting material, the reaction was partitioned between dichioromethane (2.0 mL) and saturated sodium bicarbonate (2.0 mL) . The organic layer was separated, and the aqueous layer was extracted with dichioromethane (3 X 2.0 mL) . The organic layers were dried with sodium sulfate, concentrated and purified by column chromatography on silica gel. If substrates are less reactive, α,α,-trifluorotoluene can be substituted for DCM, as it causes improved reactivity for some cases. For water-soluble starting materials, a purely aqueous reaction (1.0 mL of water) can be run and in some cases, it was also found to display improved reactivity. In lieu of a workup, these reactions can be concentrated and the product purified directly. If the addition of tert-butyl hydroperoxide is performed too rapidly, the resulting exotherm can result in reduced yield and selectivity. This is especially important on larger scales (see gram scale procedure: substrate 2), where a syringe pump can be used to meter in tert-butyl hydroperoxide.It is noted that trifluoroacetic acid (TFA) is not required in either of the above procedures. It was also found that TFA showed improved rate and conversion for selected nitrogen heteroarene substrates, but was not essential to achieve the desired reactivity for most cases. When present, TFA is typically used at about 0.25 to about 2 equivalents per equivalent of nitrogen heteroarene, and more preferably at about 0.5 to about 1.5 equivalents relative to the nitrogen heteroarene.

92%	With water; sodium hydroxide; In acetonitrile; at 20℃; for 0.166667h;	General procedure: A mixture of 8 or 10 (1 mmol), NaOH (11 mmol, 0.44 g) was dissolved in CH3CN (CH3CN/H2O 10/1, V/V, 11 mL) in an oven dried 50 mL round bottom flask containing a stir bar. Iododifluoroacetophenone (2) (2 mmol, 0.56 g), was added to the reaction mixture and stirred at room temperature for about 10 min. After the reaction was completed as indicated by TLC the reaction mixture was removed under reduced pressure. And then, the reaction mixture was diluted with water (50 mL) and extracted with EtOAc (25 mL x 3), followed by brine (50 mL). The organic extract was dried over NaSO4, filtered and evaporated under reduced pressure. The crude product was further purified by silica gel column chromatography using (pet ether/EtOAc) to furnish the S- and O-CF2H derivatives 9a-9h and 11a-11h.

Yield	Reaction Conditions	Operation in experiment
89%		General procedure: The starting material (2 mmol) was added to a sealed tube holding 20 mL of a 1:1 mixture of acetonitrile/water and KOH (40 mmol), whichwas cooled using an ice bath. The mixture was vigorously mixed for 15min and then phosphonate 1 (4 mmol) was added to the mixture in oneportion, and mixing and cooling was maintained for an additional 15 -60 min, followed by ~30 min - 2.5 h at r.t. The reaction mixture wasthen diluted with ether (10 mL) and the organic phase separated. Thewater phase was further washed with ether (10 mL). The combinedorganic phase was dried over anhydrous Na2SO4 and the solvent evaporatedto provide a crude product which was purified using columnchromatography on silica gel
