• 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).
• 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.
• 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 ɑ?-enones to give ?-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).
• 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).
