A platinum complex having dibutylgermyl ligands, [Pt(GeHBu2)2(dmpe)] (dmpe = 1,2-bis(dimethylphosphino)ethane), reacted with excess H2GeBu2at 90 °C to yield a five-membered tetragermaplatinacycle, [Pt(GeBu2GeBu2GeBu2GeBu2)(dmpe)] (6). The direct reaction of H2GeBu2with [Pt(dmpe)2] in 5:1 ratio also gave6in 67% yield. The reaction of dimethyl acetylenedicarboxylate with6caused insertion of a CC bond into a Pt–Ge bond to form a seven-membered germaplatinacycloheptene, which was characterized by X-ray crystallography. Complex6reacted with H2GePh2and H2SiPh2in 1:2 ratio to produce a mixture of tetragermane dihydride H(GeBu2)4H and bis(silyl)- or bis(germyl)platinum complexes [Pt(EHPh2)2(dmpe)] (E = Si, Ge).
