  1. Reagent for the preparation (see Appendix 4) of dimethylsilyl (DMS) derivatives, compare Hexamethyl disilazane, 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 Chlorodimethyl silane, A13113.
  2. 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):
