Summary:Three new stable germylenes, rac-1,3-di- tert-butyl-4,5-dimethyl-1,3-diaza-2-germacyclopentane-2-ylide ( 1), 1,3-di- tert-butyl-4,4-dimethyl-1,3-diaza-2-germacyclopentane-2-ylide ( 2), and rac-1,3,4-tri- tert-butyl-1,3-diaza-2-germacyclopentane-2-ylide ( 3) have been synthesized by the reaction of their corresponding dichlorides with elemental lithium. Full synthetic procedures and characterizations are described.
