1. Organogermanium compounds containing a silicon atom or a second germanium atom undergo a reaction of aluminum bromide, similar to the reaction of Vdovin, Pushchevaya, and Petrov in the series of structurally analogous organosilicon compounds. 2. Organogermanium compounds are more inclined to this reaction than organosilicon compounds, since the formation of (CH3)4Ge in this case proceeds considerably more readily than that of (CH3)4Si.
