chemistry is concerned with examples where
the attached silatrane substituent atom is that of an element more
electronegative than silicon. The current study features silylated
silatranes with a range of electropositive elements attached to the
silyl group. The resulting compounds show different degrees of electron
density on the silatrane-substituted silicon atom. This directly affects
the Si–N interaction of the silatrane which can be monitored
either by 29Si NMR spectroscopy or directly by single crystal
XRD analysis of the Si–N distance. Within the sample of study
the Si–N distance is increased from 2.153 to 3.13 Å. Moreover,
the bis(trimethylsilyl)silatranylsilyl unit was studied as a substituent
for disilylated germylene adducts.
