The reaction of chlorodimethylorganosilanes [Cl-Si(CH3)2R; R = CH3. -CH=CH2, -CH2Cl, -CH2-CH=CH2. C6H5) with magnesiumbutadiene at 0°C in toluene gives trans-1,4-bis[dimethylorganylsilyl]-2-butenes in 55-88% yield. The amount of (Z)-isomer ranges from 0 to 17% depending on the organic substituent; no 1.2-disylilated products were detected.
氯二甲基有机硅烷 [Cl-Si(CH3)2R; R = CH3, -CH=CH2, -CH2Cl, -CH2-CH=CH2, C6H5] 在0°C的托烯中与镁丁二烯发生反应,生成trans-1,4-双 [二甲基有机硅基]-2-丁烯,产率为55-88%。(Z)-异构体的含量范围为0到17%,具体取决于有机取代基;未检测到1,2-二硅基化产物。
