Desulfurization of isothiocyanates by a divalent germanium amide

Ge[N(SiMe 3 ) 2 ] 2 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 3 ) 2 N) 2 GeS] 2 in high yield. The reaction wit...

Zusammenfassung:Ge[N(SiMe 3 ) 2 ] 2 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 3 ) 2 N) 2 GeS] 2 in high yield. The reaction with tert -butylisoselenocyanate produced the related dimer [((SiMe 3 ) 2 N) 2 GeSe] 2 within 5 minutes as shown using 77 Se NMR spectroscopy. A germanium( ii ) amide abstracts a sulfur atom from isothiocyanates.
