Conclusions
The changes in the ESR spectra of 3,6-di-tert-butylpyrocatechate trifluorosilicate in the presence of electron-donor Ph3P, MeCN, and PhCN molecules indicate coordination of these molecules with the central silicon atom and subsequent opening of the chelate pyrocatechate ring with formation of phenoxyl complexes. Migration of the heteroorganic group occurs between the oxygen atoms of the pyrocatechate ligand at elevated temperatures.
