Hexamethyldisilane acts as a silylating reagent for allylic acetates, aryl halides and diketones. It is a source material for vapor deposition during silicon carbide growth. It is also used in electronic and semiconducter industries.

Precursor of TMSLi, TMSNa and TMSK by cleavage with alkyllithiums or alkoxides. Reaction of the metallated derivatives with aryl halides gives aryltrimethylsilanes: J. Org. Chem., 42, 2654 (1977). The anion adds 1,4-to ɑß-enones to give ß-silyl ketones: J. Org. Chem., 41, 3063 (1976); Tetrahedron Lett., 24, 3497 (1983). The anion may also be used to deoxygenate secondary nitroalkanes (to ketoximes), nitrones (to imines), and heterocyclic N-oxides: J. Org. Chem., 64, 2211 (1999).
Also cleaved by TBAF to give the "salt-free" silyl anion, which adds to aldehydes to give, after acid hydrolysis, ɑ-hydroxy silanes: J. Org. Chem., 48, 912 (1983). TBAF also catalyzes the silylation of OH groups under very mild conditions: Tetrahedron Lett., 35, 8413 (1994). See Appendix 4.
Couples with aryl, benzyl or allyl halides in the presence of Tetrakis(triphenylphosphine)palladium(0), 10548, to give the corresponding silanes: J. Organomet. Chem., 148, 97 (1978); 225, 331 (1982).
Aryl and alkenyl nitriles undergo ipso-silylation-decyanation, catalyzed by Chloro(1,5-cyclooctadiene)rhodium(I) dimer, 10466, to give the corresponding trimethylsiliyl derivatives: J. Am. Chem. Soc., 128, 8152 (2006).
