| | HEPTAMETHYLDISILAZANE Usage And Synthesis |
| Physical properties | colorless liquid, bp 70°Cat 25 mm Hg; its
hydrochloride salt, mp 191 °C. | | Uses | Methanamine, 1,1-Bis(trimethylsilyl) is reagent used for the preparation of N-bis(trimethylsilyl)methyl
amines, imines, as a synthetic equivalent of N-methyl, N-
(trimethylsilyl)methyl carbanion, and [N-CH] dianion synthons,
as an N-protecting group. | | Preparation | It is prepared by lithium metal mediated
reductive silylation of trimethylsilyl cyanide. |
