YieldReaction ConditionsOperation in experiment
92% With 2,2-dimethoxy-2-phenylacetophenone; In methanol; for 1h;UV-irradiation; Tri-n-butyl(2-propen-1-yl)phosphonium bromide (1.537 g,4.75 mmol), 1H,1H,2H,2H-perfluorodecanethiol (2 eq., 4.513 g,9.40 mmol), and DMPA (0.05 eq., 0.064 g, 0.25 mmol) were combinedin a 20 mL scintillation vial equipped with a magnetic stirbar and dissolved in 7.5 mL methanol to form a colorless solution.The mixture was irradiated under UV light for 1 hr with constantstirring, producing a white suspension. The suspension was transferredto a round bottom flask and solvent was removed via rotaryevaporation. The crude product was stirred with 60 mL hexanes for1 hr at room temperature, forming a mixture with two liquidphases. The top solvent layer was decanted, leaving a viscous oilthat was stirred with an additional 60 mL hexanes at 50 for 1hr. Solvent was again decanted and the purified oil was dried ona vacuum line, eventually affording a white solid that was subsequentlystored in a desiccator. Yield: white solid, 3.522 g, 92%.Melting point (DSC): 46 C. 1H NMR (400 MHz, CD3OD): dH(ppm) = 2.80 (m, 4H), 2.51 (m, 2H), 2.38 (m, 2H), 2.26 (m, 6H),1.88 (m, 2H), 1.55 (m, 12H), 1.01 (t, J = 7.0 Hz, 9H). 13C NMR(101 MHz, CD3OD): dC (ppm) = 33.36 (d, J = 17.3 Hz), 32.91 (t,J = 21.8 Hz), 24.97 (d, J = 15.6 Hz), 24.44 (d, J = 4.6 Hz), 23.29 (t,J = 4.1 Hz), 22.54 (d, J = 3.6 Hz), 19.22 (d, J = 48.5 Hz), 18.49 (d,J = 48.5 Hz), 13.70 (s). 19F NMR (376 MHz, CD3OD): dF (ppm) =-82.38, 115.21, 122.71, 122.89, 123.74, 124.27, 127.28.31P NMR (162 MHz, CD3OD): dP (ppm) = 34.16. HRMS (ESI/QTOF)m/z: [M - Br]+ calculated for C25H37F17PS: 723.2082, found:723.8196.
