Versuchsvorschrift

A solution of 1.5 g (0.005 mol) of bis(4-fluorophenyl)methyl(1H-1,2,4-triazol-1-ylmethyl)silane in 10 mL of THF was treated with n-butyllithium as described in Example 1. To this solution was added 0.63 mL (0.007 mol) of dimethyl disulfide. The reaction mixture was allowed to warm to 0°, stirred 30 minutes, then poured into 1:1 ether/hexanes, washed with 7% aqueous NaHCO3 and brine, dried over Na2SO4, filtered and evaporated. The crude product was flash chromatographed (5% ether/methylene chloride) to give 1.4 g of the title compound as a clear oil: nD 1.5750; ir (neat) 3030 (w), 2935 (w), 1587, 1496, 1230, 1160, 1106, 1035, 822 cm-1 ; nmr (CDCl3) δ 0.7 (3H, s), 2.6 (3H, s), 4.0 (2H, s), 7.1 (4H, m), 7.5 (4H, m), 7.8 (1 H, s).
