Procedure
trans-[3-((4-butylphenyl){4-[2-(4-{(4-butylphenyl)[3-((benzyl)methylsulfonio)phenyl]amino}phenyl)vinyl]phenyl}amino)phenyl]((benzyl)methyl)sulfonium triflate (20) (0.85 g 0.81 mmol) was dissolved in acetone (10 ml). To this solution was added 10 ml of an aqueous solution of sodium hexafluoroantimonate (0.84 g, 3.25 mmol). The resultant mixture was stirred two days with slow evaporation of acetone in the dark at room temperature. The mixture was allowed to cool at 0° C., the yellow oil that formed solidified. The yellow solid was collected by filtration and washed four times with water and three times with ether. NMR-pure product was obtained without further purification in 83.2% yield (0.85 g). 1H NMR (CD3COCD3, 500 MHz) δ ppm: 6.9-7.7 (m, 36H, 34 Ar—H, 2 ═CH), 5.27 (d, 2J=12.5 Hz, 2H, SCH2), 5.02 (d, 2J=12.5 Hz, 2H, SCH2), 3.52 (s, 6H, CH3), 2.63 (t, J=7.7 Hz, CH2, 4H), 1.61 (m, CH2, 4H), 1.36 (m, CH2, 4H), 0.95 (t, J=7.2 Hz, CH3, 6H)13 C NMR (CD3COCD3, 125.7 MHz) δppm: 149.3, 145.6, 143.5, 139.9, 133.5, 131.9, 130.7, 130.0, 129.8, 129.3, 127.9, 127.7, 127.1, 126.5, 125.6, 124.5, 123.8, 123.4, 121.7, 51.0, 34.7, 33.5, 24.5, 22.1, 13.3.
