79% | zinc diiodide; In dichloromethane; | EXAMPLE 13 2-(5-Fluoro-2-methoxyphenyl)-2-trimethylsiloxyethanenitrile By the procedure of Example 1, except that a reaction time of 4 days at room temperature was employed, <strong>[19415-51-1]5-fluoro-2-methoxybenzaldehyde</strong> (9.5 g., 0.062 mole) in 50 ml. of methylene chloride was reacted with trimethylsilylcarbonitrile (7.3 g., 0.074 mole) in the presence of a catalytic amount of zinc iodide to produce 2-(5-fluoro-2-methoxyphenyl)-2-trimethylsiloxyethanenitrile [12.5 g., 79%; oil; m/e 253; ir (CH2 Cl2) 1504, 1200 cm-1 ]. |
79% | With zinc(II) iodide; at 20℃; for 1h; | A solution of ZnI2 (1.6 mg, 0.01 mmol), <strong>[19415-51-1]5-fluoro-2-methoxybenzaldehyde</strong> (1.54 g, 9.99 mmol) in trimethylsilanecarbonitrile (1.5 mL, 11.25 mmol) was stirred for 1 h at room temperature. The resulting mixture was concentrated under vacuum. The resulting crude product was purified by silica gel chromatography (eluting with 1:1 ethyl acetate/petroleum ether) to afford 2-(5-fluoro-2-methoxyphenyl)-2-[(trimethylsilyl)oxy]acetonitrile as a white solid (2.0 g, 79%). |
