Abstract The reactions of hydro, organyl and halosilatranes with nucleophiles have been studied. Substitution involving cleavage of equatorial Si O bonds is always observed. Silatranes exhibit reactivity quite different from that of analogous trialkoxysilanes or anionic pentacoordinate silicon compounds.
