The compound (C6H5)2Ge(CH2)4 has been burnt in an aneroid combustion bomb and the enthalpy of sublimation measured by a combination of d.s.c. and effusion: ΔfH0m = (34.3 +/- 10.0) kJ * mol-1; ΔfH0m = (138.9 +/- 10.5) kJ * mol-1.The gas-phase molar enthalpy of formation has been used to investigate strain in the ring system.

A dirhodium-catalyzed, ?-selective C-H amination of organosilicon compounds has been developed. Primary C(sp3)-H bonds of silylethyl groups and secondary C(sp3)-H bonds of silacycloalkanes can be selectively converted to C-N bonds at the ?-position of the silicon atoms. The experimental data and theoretical calculations indicate that the strong s-donor ability of the carbon-silicon bonds is responsible for the ?-selectivity. Kinetic isotope effects clearly demonstrate that the C-H bond cleavage step is not turnover-limiting, but selectivity-determining.

The reactions of diarylgermanes with alkali metals in HMPA/THF or THF were found to give the corresponding diarylgermylenedialkali metals in high yields.Diphenylgermylenedipotassium reacted with aryl halides or carbonyl compounds to give reduction products predominantly.With alkyl halides, diphenylgermylenedipotassium gave mainly substitution products.
