The trapping of a transient base-stabilized germylenylsilylene by elemental tellurium and arylazide is described. The reaction of the potassium 2-imino-5,6-methylenedioxylphenylgermylidenide [L iminophenyl GeK] (L iminophenyl = 2-imino-5,6-methylenedioxylphenyl) with the amidinato chlorosilylene [L amidinate SiCl] {L amidinate = PhC(NtBu) 2 } in THF at-78°C afforded the transient base-stabilized germylenylsilylene [L amidinate SiGeL iminophenyl ] (3). It was unstable in solution, but can be trapped by reacting with elemental tellurium and 2,6-diiso-[a] Dr.
