Reagent for the preparation (see Appendix 4) of dimethylsilyl (DMS) derivatives, compare Hexamethyl­disilazane, A15139. With allylic and homoallylic alcohols, the products can undergo Pt- or Rh-catalyzed intramolecular hydrosilylation, providing a regioselective route to 1,3-diols: J. Am. Chem. Soc., 108, 6090 (1986). For an example of this reaction, see Chlorodimethyl­silane, A13113.

The potassium derivative, formed by reaction with KH in THF, reacts with alkyl halides to give, after hydrolysis, high yields of primary amines, thus providing a convenient alternative to the classical Gabriel method. Other silazanes, including hexamethyldisilazane, give lower yields: Synthesis, 150 (1995):
