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.
