Ge[N(SiMe)] reacts with isocyanates but its reactivity with the related heavier congeners has not been explored. Its reaction with tertiary isothiocyanates results in the abstraction of the sulfur atom to yield a germanium(IV) dimer [((SiMe)N)GeS] in high yield. The reaction with -butylisoselenocyanate produced the related dimer [((SiMe)N)GeSe] within 5 minutes as shown using Se NMR spectroscopy.
