MEDIUM-SIZED SILICON-CONTAINING RINGS. IV. SILOCANE-SILATRANE TRANSFORMATIONS
We have discovered an intramolecular condensation of trimethylsilyl ethers of silocines with a phenyl substituent on the silicon atom that leads to the corresponding silatranes.For the preparation of N-(hydroxyethy) derivatives of silocines we have, for the first time, used the cyclosilylation of triethanolamine with a bis(dialkylamino)silane.It was found that in the exothermic reaction of trialkoxyalkylsilanes with N-(hydroxyethyl) derivatives of silocines and their trimethylsilyl ethers the yield of silatranes is only slighthly dependent on the nature of the substituent both in the silocines and in the alkoxysilanes.
