- Useful reagent for the silylation of alcohols and carboxylic acids: Synthesis, 807 (1981). See Appendix 4. Generally no catalyst is required and the urea formed as by-product can be removed by filtration. For O-silylation catalyzed by TBAF (0.02 equiv.) under mild conditions, see: Tetrahedron Lett., 35, 8409 (1994). Review: Synthesis, 357 (1998).
