Reaction Conditions:
Stage #1:isopropyl chloride with magnesium in tetrahydrofuran at 40 - 65;Inert atmosphere;
Stage #2: with trichlorosilane in tetrahydrofuran;hexane at -10 - 0;Inert atmosphere;Temperature;
Steps:
4
To the under the N2 protection of 500mLAdd magnesium shoulder in four bottles5. 10 g (0.21 mol) and 15 mL of tetrahydrofuran, 2-chloropropane (16. 81 g, 0.241 mol) was added to the constant-dropping funnel. Approximately 4 mL of 2-chloropropane (about one-fifth of the total 2-chloropropane) was rapidly added to the 500 mL four-necked flask through a constant-dropping funnel and the remaining 2-chloropropane was diluted with 90 mL of tetrahydrofuran. The reaction was initiated by heating to 40-65 ° C. After initiation, a solution of the remaining 2-chloropropane in tetrahydrofuran was added dropwise and the temperature was maintained at 40-65 ° C. After the addition is complete, heat the reaction at 40-65 ° C for 0.5-lh and then cool to 20-30 ° C.A solution of 13. 68 g (0. l mol) of trichlorosilane and 41. 04 g of n-hexane was added dropwise. The system was highly exothermic and produced a large amount of white solid, which was controlled at a temperature of -10 to 0 ° C. Drop, the reaction of 0. 5-lh, filter, wash the filter cake with n-hexane, combined filtrate, concentrated most of the solvent, and then distillation, collecting 110-140 ° C distillate, that is, products. Yield 75%, purity 95.0%
