REACTIVITY OF AMINO-SUBSTITUTED DISILANES GERMYLSILANES WITH TRIFLUOROMETHANESULFONIC ACID

Aminosubstituted disilanes and germylsilanes react with trifluorometha nesulfonic acid under formation of the corresponding oligomeric trifla te derivatives. The displacement of an amino group progresses signific antly faster than the substitution of a phenyl group at the silicon at om. For that reason the exchange of amino substituents often leads to other products than the exchange of a phenyl group. The oligomeric str uctures are characterised by Si-29 NMR spectroscopy.
