반응 단계
The synthesis of ClSi2(NMe2)5 has been done from the ammonolysis of hexachlorodisilane and lithium dimethylamide. Hexachlorodisilane (HCD) is used as the starting material so that the Si-Si direct bond remains in the molecule. n-hexane is used as a solvent and cooled at 0° C. A mixture of pentakis(dimethylamino) chloro disilane and hexakis(dimethylamino) disilane is obtained. Lithium dimethylamide is added to form a “lithium dimethylamide solution”. HCD is added dropwise in the 0° C. lithium dimethylamide solution. Then the solution is stirred for 2 h at 0° C. then for 15 h at RT. The salt LiCl is then removed from the solution, and the n-hexane removed in vacuo. The resulting ClSi2(NMe2)5 and other byproducts are separated by fractional distillation.
