Darstellung
synthetischetert-butyldimethylsilyl chloride (TBSCI) was synthesized by the reaction of tert-butyllithium with dichlorodimethylsilane.The pentane solution of dichlorodimethylsilane was cooled to 0°C, and the pentane solution of tert-butyllithium was added dropwise with stirring under nitrogen. The temperature was maintained at 0 °C, stirred for 1.5 h and then heated to 25 °C, and the reaction was continued for 48 h. Distillation, collect 125 ℃ (97.5kPa) fractions, stand to solidify, and obtain tert-butyldimethylsilyl chloride. Yield 70%.
