Cohydrolysis of phenyltrichlorosilane with phenyl(fluoro)dichloro- and phenyl(difluoro)-chlorosilanes and thermolysis of the formed siloxanes leading to the formation of phenyl(difluoro)chlorosilane are studied. The scheme of thermal decomposition of disi

Heterocyclic cage compounds of type I (compounds 8 - 10) have been prepared by condensation reactions of 1,2,2-trifunctional disilanes Me(R)XSiSiMeX2 (R = Me, Ph, OEt; X = NMe2, OEt) with triethanolamine using the "Dilution Principle".The starting compounds are obtained by Si - Me cleavage of Si2Me6 with acetylchloride/AlCl3 followed by either aminolysis with HNMe2 or alcoholysis with EtOH. 1H NMR spectra indicate N -> Si(1) intraction with the more acidic Si atom in 8 and 9.This result is proved by the X-ray structure analysis of 8 (monoclinic, P 21/c; a = 7.088(2), b = 15.070(4), c = 12.701(4) Angstroem, β = 104.96(2) at -130 deg C, Z = 4); the Si(1) *** N distance is found to be 2.768 Angstroem, connected with a significant angular distortion of the tetrahedral coordination around Si(1) towards a trigonal bipyramid.In compound 10, too, N -> Si(1) coordination is observed at room temperature in spite of almost equal acidity for both Si atoms.This can be explained by the preference of 5- over 6-membered chelating ring systems.At higher temperatures the 1H NMR spectra show a fluctuation of the N-donor between the two Si centres. - Key words: Silatranes, Transanular N -> Si-Interactions, NMR Spectra, X-Ray
