reaction of germanium atoms with organic halide by co-condensation under vac. at 77 K; GC-MASS;

in tetrachloromethane; water Kinetics; an aliquot of aq. soln. containing varius concens. of hydrohalogenic acid and germanium compd. is shaken with an aliquot of CCl4 for 30 min in a centrifuge tube at 25°C; after phase sepn., the germanium concen. in both the phases is determined with an inductivity coupled argon plasma emission spectrometer;

in tetrahydrofuran addn. of 10-fold excess of MeI to Ge-atom/THF slurry (Ar atmosphere), stirring (50°C, 5 h); GC-MS, GLC;
