摘　　要：以正己烷为溶剂,六甲基二硅氮烷((Me3Si)2NH)与二甲基二氯硅烷((CH3)2SiCl2)在正丁基锂的催化下常温发生反应,合成N,N-二(三甲基硅基)-氨基-氯代二甲基硅烷.反应经正交实验确定正丁基锂的最佳浓度是1.5 mol/L,反应物最佳摩尔比n((Me3Si)2NH)∶n((CH3)2SiCl2)为0.83∶1,溶剂正己烷的体积为140 mL,产品的最高产率达74.81%,并经IR和1H-NMR表征结构.N,N-bis（trimethylsilyl）-amino-chloro-dimethyl silane was synthesized from hexamethyl disilazane（（Me3Si）2NH）and dimethyldichlorosilane（（CH3）2SiCl2） with hexane as solvent,n-BuLi as a catalyst for the reaction at room temperature.The factors affecting the yield by orthogonal experiment were investigated,and the results showed that concentration of n-BuLi was 1.5 mol/L,the best molar ratio of reactant n（hexamethyl disilazane）∶n（dimethyldichlorosilane） was 0.83∶1,volume of solvents was 140 mL,the highest yield of the product was up to 74.81 %,and IR and 1H-NMR.was employed to characterize the structure of the product.
