s, Cp2EC4R′4 (E = Ti, Zr, Hf; R′ = Ph, Me) with various halogermanes has been studied. The tetrahalides GeCl4 and GeBr4 undergo the E/Ge exchange reaction at room temperature, but the trihalides RGeCl3 and dihalides R2GeCl2 (R = Me, Ph) are less reactive. Some germoles were found to be unstable. A phenyl group on the germanium atom stabilizes the 2,3,4,5-tetramethylgermoles with a GeH (HPhGeC4Me4)
