Several new compounds containing both chloro and dimethylamino groups linked to silicon have been prepared. The general method involved reacting a solution of the appropriate polychlorosilane in ether at ca. - 50° with a chilled ethereal solution of dimethylamine. Prepared in this fashion were CH3Si(NMe2)Cl2, CH3Si(NMe2)2-Cl, PhSi(NMe2)Cl2, PhSi(NMe2)2Cl, CH3(H)Si(NMe2)Cl, (CH3)2Si(NMe2)Cl, CH2CH(CH3)Si(NMe2)Cl
已经制备了同时与硅连接的同时含有氯和二甲基氨基的几种新化合物。一般的方法包括使合适的聚氯硅烷在乙醚中的溶液在约200℃下反应。-用二甲胺的乙醚溶液冷却50°。以这种方式制备的是CH 3 Si(NMe 2)Cl 2,CH 3 Si(NMe 2)2 -Cl,PhSi(NMe 2)Cl 2,PhSi(NMe 2)2 Cl,CH 3(H)Si(NMe 2)氯,(CH 3)2的Si(NME 2)氯,CH 2 CH(CH3)Si(NMe 2)Cl和Ph 2 Si(NMe 2)Cl。这些化合物的光谱与全卤和全胺系列光谱的比较表明,用NMe 2代替Cl导致与硅连接的其他基团的共振发生高场移位,该移位与在取代CH 3时观察到的平行对于Cl。红外光谱中的ν(SiH)和NMR光谱中的δ(SiH)呈线性关系。
