The C≡C bonds of various alkynylgermanes [Cl(H)Ge(C≡C–R1)2, Cl2Ge(C≡C–R1)2 with R1 = nBu, SiMe3, and Ge(C≡C–R1)4 with R1 = SiMe3] undergo 1,1-carboboration when treated with an excess of triethylborane at 80–110 °C. All pure final products with R1 = SiMe3 possess germole-derived structures. Intermediates and side products as a result of lost stereoselectivity of the 1,1-carboborations could be detected and in some cases identified by NMR spectroscopic studies of the reaction solutions.
