Synthesis and isolation of a cyclic bis-vinyl germylene via a diazoolefin adduct of germylene dichloride

Abstract

Since the successful isolation of various stable diazoolefins, an array of complexes containing these promising ligands have been synthesized. We herein report the synthesis, characterization, and structures of neutral group 14 diazoolefin complexes and the subsequent transformation into a new cyclic bis-vinyl germylene.
