Abstract

The ligand properties of a series of aryl oligogermanes R₃Ge-GeAr₃, 3–7 [Me₃Ge-GePh₃ (3), Me₃Ge-Ge(pTol)₃ (4), Ph₃Ge-GePh₃ (5), (C₆F₅)₃Ge-GePh₃ (6), Ph₃Ge-GeMe₂GePh₃ (7)] for the synthesis of transition metal carbonyl complexes such as R₃Ge-GeAr₂(R′C₆H₄-η⁶)M(CO)₃ (M = Cr, 3a–7a; M = Mo, 3b; M = W, 3c) were investigated. The target complexes were obtained in moderate yields using several different synthetic approaches. The physicochemical properties of these new derivatives were investigated by IR, UV/Vis, NMR spectroscopy, electrochemistry, and DFT calculations. The molecular structures of 3c, 4a, and 5a were studied by single-crystal X-ray diffraction analysis. A comparative analysis of donor and acceptor properties of aryl oligogermanes as ligands for transition metal carbonyl complexes is reported.
