Isolation of a Cyclic (Alkyl)(amino)germylene.

ABSTRACT

A 1,4-addition of a dichlorogermylene dioxane complex with α,ß-unsaturated imine 1 gave a dichlorogermane derivative 2 bearing a GeC3N five-membered ring skeleton. By reducing 2 with KC8, cyclic (alkyl)(amino)germylene 3 was synthesized and fully characterized. Germylene 3 readily reacted with TEMPO, N2O and S8, producing the 12 adduct 4, the oxo-bridged dimer 5 and the sulfido-bridged dimer 6, respectively.
