HandyStep - Reference Information
| preparation | first, the metal magnesium and 2-chloropropane were reacted to synthesize isopropyl magnesium chloride, and then in the presence of weak polar solvent, triisopropylsilane was prepared from isopropylmagnesium chloride and trichlorosilane at low temperature. The invention generates triisopropylsilane by a two-step synthesis method, and when preparing triisopropylsilane, a weak polar solvent that does not affect the solubility of the solvent is used to change the polarity of the solvent, in order to prevent the occurrence of side reactions, the difficult-to-separate impurities in the reaction process are greatly reduced. Finally, high-purity triisopropylsilane can be obtained by simple distillation, and the purity of the product can reach 99%. |
| Use | peptide synthetic protectant. Large Volume isopropyl group (compared with ethyl group) can achieve more selective reduction reaction? Should be (e. G., beta-selective reduction of heterotopic C- phenyl ketals), but not reduce their activity (e. G., trifluoromethane? Sulfonic acid ketone catalytic type reduction etherification). Highly non-? N-heterocyclic carbene complex-catalyzed trans-1, 2-diol? Enantioselective preparation. |
