Komponenten

Versuchsvorschrift

31.5 ml of hexamethyldisilazane (0.15 mmole) were added to a refluxing suspension of a mixture of 50 ml of toluene and 19.80 g (0.20 mole) of succinimide and 458 mg of saccharin (2.5 mmoles) and refluxing was continued for 2 hours. Fifteen minutes after the addition of the silylating agent, a clear, light yellow solution was obtained which turned brown when refluxing was continued. The reaction mixture was cooled, filtered and after evaporation of the solvent, the residue was vacuum distilled to obtain 31.04 g (90.8%) of N-trimethylsilylsuccinimide boiling at 86°-88° C. at 1.3 mm Hg.
