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 germyl dichlorides with elemental lithium. Full synthetic procedures and characterizations are described.
