• Access to Fully Alkylated Germanes by B(C₆F₅)₃-Catalyzed Transfer Hydrogermylation of Alkenes

  Various cyclohexa-2,5-dien-1-yl-substituted germanes are shown to serve as easy-to-handle surrogates of hydrogermanes, including gaseous MeGeH3 and Me2GeH2; The Ge-H functional group is liberated by treatment with catalytic amounts of B(C6F5)(3) and participates in situ in the B(C6F5)(3)-catalyzed hydrogermylation of alkenes. The range of suitable alkenes is broad, and the overall procedure provides a convenient access to tetraalkyl-substituted germanes at room temperature. Transfer hydrogermylation of internal alkynes works equally well and selectively forms the trans or cis diastereomer depending on the electronic bias of the C C bond.
• H–Ge bond activation by tungsten carbonyls: An experimental and theoretical study

  The activation of the Ge-H bond and the formation of several hydride complexes, characterized by high-field resonances, have been detected during the H-1 NMR spectroscopy monitoring of the photochemical reaction of Et3GeH and Et2GeH2 with W(CO)(6) and the norbornadiene complex [W(CO)(4)(eta(4)-nbd)]. The activation of the Ge-H bond of triethylgermane in the photochemical reactions of tungsten(0) complexes has been applied in the hydrogermylation of norbornadiene (nbd), which leads to the formation of endo-triethylgermylnorbornene as the major product. The complex [W(mu-eta(2)-H-GeEt2)(CO)(4))(2)] has been fully characterized by NMR spectroscopy and by a single-crystal X-ray diffraction study. Evidence for the hydride ligand of the W(mu-eta(2)-H-GeEt2) group has been provided by H-1 NMR spectroscopy (delta = -9.02, (1)J(H-W) = 31 Hz) and by DFT calculations. A DFT study of the structural properties and H-1 NMR chemical shifts of several possible intermediate a and hydride complexes formed during the photochemical reaction of W(CO)(6) and Et2GeH2 has been performed.
