Double Germylation of Unsaturated Carbon Compounds with Digermanes in the Presence of Palladium and Platinum Catalysts

Double germylation of acetylenes, isoprene, and ethylene with 1,2-dichloro-1,1,2,2-tetramethyldigermane proceeds in the presence of palladium- and platinum-phosphorus ligand complexes to afford α,ω-bis(chlorodimethylgermyl) compounds in moderate to good yields.
