substituted compounds exhibit a degenerate equilibrium which involves a planar germacyclopent-3-ene transition state. Reaction of 1-halogeno-1-(transition metal carbonyl)-substituted germacyclopent-3-enes with different transition metal carbonylate anions results in formation of mixed-metal carbonyl derivatives and reduction with LiAlH4 results in formation of a germanium hydride.
