Procedure

In accordance with J. P. Mooser, H. Noth and W. Tinhof in Z. Naturforsch. B 29, 166 (1974), 68.98 g (0.406 mol) silicon tetrachloride and 12.3 g (0.076 mol) hexamethyl disilazane are combined in a 250 ml three-necked flask and stirred for 14 hours at room temperature. Subsequent fractional distillation in a short Vigreux column gives 15 g (88%) of the colorless liquid.
