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...
