Trimethylsilylazide and hexamethyldigermoxane undergo exchange at room temperature to stoichiometrically yield trimethyl(trimethylsiloxy)germane and trimethylgermyl azide. The rates of this second order reaction have been measured at several temperatures between 21 and 53° C. An Arrhenius plot of this data gives the following activation parameters: ΔS‡ = −40 ± 2 eu. The large negative entropy of activation
