Mass-spectrometric study of intramolecular coordination Si → O Interaction in gaseous (aroyloxymethyl)trifluorosilanes and methyl(aroyloxymethyl)fluorosilanes

Conclusions Mass-spectrometric criteria were developed for the assessment of the intramolecular coordination Si O interaction in the molecules of (aroyloxymethyl)trifluorosilanes and their analogs, methyl(aroyloxymethyl)difluorosilanes, and dimethyl(aroyloxymethyl)fluorosilanes. The successive replacement of fluorine atoms by methyl groups leads to a decrease in the intramolecular interaction of the silicon and carbonyl oxygen atoms.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1508–1511, July, 1987.
