产品应用

⑴.也称二(三甲基硅基)氨基锂。熔点71～72℃。沸点114～116℃(133.322Pa)。自燃，惰气保护下密封贮运。对空气与水敏感。以硅氨在乙醚中与金属锂反应而得。
⑵.用于醛醇缩合，是常用的有机碱。例如形成乙炔化锂，或者制备烯醇锂盐。
⑶. 双(三甲基硅基)氨基锂可用于制备低配位数的配合物，因为配体(TMS)2N-的位阻很大。这样的例子有M[N(TMS)2]3（M = Sc, Ti, V, Fe ；TMS = (CH3)3Si)）。与三甲基氯硅烷反应产生三(三甲基硅基)胺，其中氮的配位数为3，空间构
非亲核性强碱，可用于形成烯醇的反应，烯醇酯立体专一克莱森重排反应，将醛转化为硅亚胺的反应，生成缩水甘油酸酯的反应，β内酰胺的反应，芳基烷基醚的选择性断裂反应。
