The resultant solutionwas stirred at room temperature for 15 min, then a further portion of TMSN3 (50 μL, 0.375 mmol, 0.75eq) was added. The solution was stirred for a further 45 min, filtered through a silica plug, eluting withEtOAc (50 mL) and volatiles removed under reduced pressure to yield the desired sulfonyl azide. |

80% | With potassium fluoride In acetone at 60℃; for 8 h; Reflux | p-Nitrobenzenesulfonyl chloride (5.00 g, 22.6 mmol) and KF (3.39 g, 67.8 mmol) (1:3) were added into a 50 mL round bottom flask with 30 mL of acetone. The mixture was refluxed at 60 °C for 8 h. A light green solid (3.81 g, 82percent) was obtained after removing the solvent and sublimation under high vacuum at 80 °C. p-Nitrobenzenesulfonylfluoride (10.0 g, 45.2 mmol) was added under N2 to a 250 mL 3-necked flask. The flask was cooled to -60 °C and 30 mL of ammonia was condensed into the reactor. The mixture was allowed to slowly warm to 22 °C and stand for 8 h. The product was washed 3* with 20 mL of water to remove the NH4F. The solid, yellow product (7.55 g, 81percent) was obtained by drying under vacuum for 24 h at 22 °C. p-NO2PhSO2F: 19F NMR (CD3CN) δ 65.7(s); 1H NMR (CD3CN) δa 8.46 (2H, d), δb 8.27 (2H,d), Jab = 8 Hz. (Note: The 1H represent an aa'bb' spin system but it appears as a deceptively simple ab system with J/δ near 0.5. The δa,b for all compounds are taken as the midpoint of the second order doublets as an approximation as if it is a classic ab spin system. The Jab is assigned as that of a classic ab spin system. No effort was made to analyze the spectra further.) p-NO2PhSO2NH2: 1H NMR (CD3CN) δa 8.34 (2H, d), δb 8.06 (2H,d), Jab = 11 Hz, δNH2 5.90 (2H,s). |

6.73 g | at 60 - 125℃; for 8 h; Sealed tube | General procedure: A stainless steel cylinder was charged with 10.00 g(33.00 mmol) of 4-nitrophenyl disulfide (1a), 100 mL of R-113,150.0 g (1.030 mol) of AgF2, and 3 glass slides (25 cm 75 cm)containing a 100 nm coinage metal film (either Cu, Ag, or Au),which is approximately 1 106 g of Ag. The coinage metals werevapor deposited onto Cr-primed glass microscope slides underhigh vacuum conditions. The reaction cylinder was then sealed andheated to between 60 and 65 8C for 2 h, agitating intermittently.After the initial heating the temperature was raised and heldbetween 120 and 125 8C for 6 h, agitating intermittently. Once thissecond heating phase was completed, the cylinder was allowed tocool to room temperature. The CFC 113 was recovered by vacuumtransfer to avoid any loss. The contents of the cylinder wereextracted with chloroform, and the recovered silver salts (amixture of AgF2 and AgF) were washed 3 times in 50 mL each ofchloroform. The chloroform was then partitioned with a 10percent (byweight) solution of NaHCO3, and the aqueous layer was verified tobe alkaline using pH paper. The chloroform layer was reduced byrotary evaporation, and the resulting yellow oil was purified bycolumn chromatography (60-mesh silica gel eluted with 9:1hexane:benzene). All pure fractions of 4-nitro-pentafluorosulfa-nylbenzene (3a) were combined and crystallized in hexane. MultinuclearNMR was used to verify the identity of the crystals. Theyields of the experiments, performed in triplicate are presented inTable 1. The yields 3a from the individual experiments for thecopper film were 5.94 g, 5.81 g, and 6.73 g, respectively, while theyields of 3a for the three silver film experiments were 7.24 g,7.00 g, and 6.85 g, respectively. And finally, the yields of 3a fromthe three gold film experiments were 8.21 g, 7.88 g, and 7.88 g,respectively. |
