- BSA catalyzes the acylation of acylphosphoranes with activated derivatives of carboxylic acids. Subsequent ozonolysis, or oxidation with singlet oxygen or dimethyldioxirane, provides a route to 1,2,3-triketones: J. Org. Chem., 54, 2785 (1989); 60, 8231 (1995):
- Powerful silylation reagent for a wide range of functional groups under mild conditions. See Appendix 4. Reviews: J. Prakt. Chem./ Chem. Ztg., 337, 332 (1995); Synthesis, 357 (1998). Unlike halosilanes, silylated amides often need no added base catalysts. For an example of use without added solvent or catalyst for the silylation of a tertiary ɑ-hydroxy ketone, see: Org. Synth. Coll., 7, 381 (1990). Silylating power can be increased in polar solvents such as DMF or acetonitrile, or by addition of acidic catalysts, often TMS chloride, or an acid such as TFA or HCl.
