W. Uhlig, REACTIVITY OF AMINO-SUBSTITUTED DISILANES GERMYLSILANES WITH TRIFLUOROMETHANESULFONIC ACID, Journal of organometallic chemistry, 463(1-2), 1993, pp. 73-76
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.
