Conditions | Yield |
diethylamine With n-butyllithium In hexane at -60℃; for 15h; Inert atmosphere; Large scale; With Dichlorosilane In hexane at -60℃; for 15h; Temperature; Inert atmosphere; Large scale; Experimental Procedure Under a nitrogen atmosphere, was added 5000ml of n-butyllithium in n-hexane in the reaction vessel, at a concentration of 2.5 moles per liter. Under stirring, 1000 g of diethylamine was added dropwise to the reaction kettle to control the dropping rate to prevent the temperature of the system from being kept at -60 ° C. After the dropping was completed, the temperature inside the kettle was kept at -60 And the mixture was stirred for 15 hours. Then pass into dichlorosilane 690 grams, control passed into the kettle to maintain a speed of -60 , and finally stirred at -60 after 15 hours, warmed to room temperature. Hexane solvent was distilled off at atmospheric pressure and then vacuum distilled bis (diethylamino) silane, distillation pressure 15mmHg, distillation temperature of 70 . To give product 990 g, yield (with respect to the weight of silicon molar ratio) was 91.1%. | 91.1% |
With ethylene bis(tetrahydroindenyl)titanium dichloride; 4-fluoro-benzamidoxime; zinc 2-ethylhexanoate; Dichlorosilane; copper(II) nitrate; lithium tetraphenylborate tris(1,2-dimethoxyethane) In hexane; water at 60 – 120℃; for 5h; Temperature; Reagent/catalyst; Inert atmosphere; | 89% |
With Dichlorosilane In hexane at -25℃; for 3h; Inert atmosphere; | 75% |
