From the copper-catalyzed reaction of germanium powder with dibromomethane at 310 °C a mixture of alkylbromogermanes is obtained. The major products are CH₃GeBr₃, Br₃GeCH₂Br (1), CH₂(GeBr₃)₂ (2) and (CH₂GeBr₂)₃ (3). The product distribution parallels the analogous reaction with dichloromethane reported previously. All com pounds were characterized by analytical and spectroscopic data, and can be converted into the corresponding hydrides.
