42% | Stage #1: With tin(IV) chloride In dichloromethane at 20℃; for 2 h; Inert atmosphere Stage #2: With 1-hydroxy-3H-benz[d][1,2]iodoxole-1,3-dione In water; dimethyl sulfoxide at 20℃; for 2 h; |
General procedure: In a round-bottomed flask equipped with a stirring bar and rubber septum was placed a 1 M solution of SnCl4 in anhydrous CH2Cl2 (1 mL, 1 mmol). To this solution was added PhSCF2H (1; 240.2 mg, 1.5 mmol) in anhydrous CH2Cl2 (1.5 mL), followed by a solution of an aromatic compound (0.5 mmol) in anhydrous CH2Cl2 (1 mL). The reaction was allowed to proceed for 2 h before it was quenched with a solution of IBX (140 mg, 0.5 mmol) in DMSO/H2O (4 mL; 3:1 v:v). After 2 h of stirring at rt, the reaction mixture was quenched by addition of a saturated aqueous solution of sodium thiosulfate (10 mL), then basified with a saturated aqueous solution of sodium hydrogen carbonate (10 mL), followed by stirring and extraction with CH2Cl2 (3 × 10 mL). The combined organic layers were washed with water (3 × 10 mL) and brine (10 mL), dried (anhydrous MgSO4), filtered and concentrated (aspirator). The residue was purified by PTLC, radial chromatography or column chromatography to furnish analytically pure product. |

88% | With 3-chloro-benzenecarboperoxoic acid In dichloromethane at 0 - 20℃; for 24 h; | To a solution of difluoromethyl phenyl sulfide 2 (3.98 g, 25 mmol) in dry CH2Cl2 (69 mL) at 0°C, a solid m-CPBA (15.9 g, 92.0 mmol) was added portionwise. The reaction was then warmed to room temperature and left for overnight stirring. CH2Cl2 (50 mL) was then added and the mixture was washed with 10percent aqueous Na2SO3 (2 100 mL), 5percent aqueous NaHCO3 (4 50 mL) and brine(2 100 mL), respectively. Organic layer was dried (Na2SO4) and concentrated under reduced pressure. The residue was purified by silica gel column chromatography using CH2Cl2 and hexane as eluents (3:1). Rf = 0.40 (CH2Cl2/hexane, 3:1).Yield: 4.24 g, 22.1 mmol, 88percent. 1H NMR (300 MHz, CDCl3): d 8.01 (dt, J = 8.7; 1.7 Hz, 2H, HAr),7.85–7.78 (m, 1H, HAr), 7.72–7.62 (m, 2H, HAr), 6.20 (t, J = 53.4 Hz,1H, CF2H); 13C NMR (101 MHz, CDCl3): d 136.0 (s, CAr), 131.9 (s,CAr), 130.8 (s, CAr), 129.7 (s, CAr), 114.8 (t, J = 285.9 Hz, CF2H); 19FNMR (282 MHz, CDCl3): d 122.1 (d, J = 53.4 Hz, 2F, CF2H).

83% | With 3-chloro-benzenecarboperoxoic acid In dichloromethane | EXAMPLE 2 Difluoromethyl Phenyl Sulfone A solution of 2.0 g (12 mmol) of difluoromethyl phenyl sulfide in 20 mL of dichloromethane was cooled to 0°-5° C. and treated portionwise with 5.4 g (27 mmol) of 85percent meta-chloroperbenzoic acid. The mixture was allowed to warm to room temperature, stirred for 4 hours, treated with an additional 1.1 g (5.4 mmol) of 85percent meta-chloroperbenzoic acid, and stirred overnight. Filtration and washing of the filter cake with 30 mL of dichloromethane gave a solution which was washed with three 25 mL portions of saturated NaHCO3 and one 25 mL portion of water, dried (MgSO4), and concentrated in vacuo. The residue was purified by flash chromatography on 50 g of silica gel (eluted with 25percent dichloromethane, 75percent petroleum ether) to give 1.92 g (83percent yield) of difluoromethyl phenyl sulfone as a colorless liquid: IR (neat) 3069, 1771, 1447, 1348, 1301, 1162, 1113, 1077, 760, 725, 685, 621, 606, 557, 545, 515, cm-1; 1 H NMR (CDCl3) δ6.29 (t, 1H, JHF =54Hz), 7.50-8.10 (m, 5H); mass spectrum (70 eV) m/e (relative intensity) 192 (22, M+), 141 (45), 77 (100), 51 (54). |
