Summary

  1. 1.

    Shielded phenols containing silicon and/or germanium have been found to rearrange to phenoxysilanes or phenoxygermanes under the influence of complex formation with oxygen.

     
  2. 2.

    The silicon- and germanium-containing phenols form π complexes with oxygen in which the oxygen acts as an acceptor. The constants of complex formation have been determined.

     
  3. 3.

    Silicon- and germanium-containing shielded phenols, when exposed to elevated temperatures or the action of bases, rearrange to phenoxysilanes or phenoxygermanes. The germanium-containing phenols are more stable at high temperatures than are the silicon-containing phenols, but are rearranged more readily under the influence of organic bases. The p isomers are more stable than the o isomers.
