Abstract

Bis(triethylgermyl)- and bis(trimesitylgermyl)-carbodiimides are easily formed either by transmetallation or transamination reactions. (Hydrogeno)triethyl- or trimesitylgermyl-cyanamides are characterized in the dehydrohalogenation reaction between cyanamide and triethyl- or trimesityl-chlorogermanes. According to a single X-ray diffraction analysis, bis(trimesitylgermyl)carbodiimide is monomeric and the GeNCNGe framework is not linear, in contrast to tin and silicon analogues, respectively.
