Tetrahydrofuran → 3-Chloropropylmethyldivinylsilane

関与物質

反応手順

The above-synthesized 3-chloropropyldichloromethylsilane (3) (9 g, 52.2 mmol) was dissolved in 50 mL of THF, to which 1.6 M vinylmagnesium chloride (98 mL, 157 mmol) was then slowly added at 0°, and the mixture was stirred for 2 hours. After the reaction, the organic layer was extracted with NH4Cl aqueous solution and ether, and washed with saturated NaCl. The washed organic layer was dried with anhydrous MgSO4 and then filtered through celite to remove MgSO4. After evaporating the solvent, and the resulting residue was purified by column chromatography (n-Hexane, Rf=0.36) to give 8.3 g (91% yield) of pure 3-chloropropylmethyldivinylsilane (4).
