Ligands germyl

Scheme 59. Proposed pathway for the germyl ligand displacement in germylpentacar-bonylmolybdenum anion.

The stereochemistry of displacement of chiral germyl ligand in germanium transition metal complexes [which has been reviewed elsewhere (12)] will also be discussed here, since silicon and germanium resemble each other and since complementary experiments have been undertaken.

The RCS XH salts (X = piperidine) also react with chlorotrimethyl-germane to give the complexes (RDta)Ge(Me)3 (R = tolyl, Ph, p-Cl—Ph). These complexes show two intense bands in the IR spectra at 1240 and 1050cm 1 (silyl esters) and 1220 and 1050 cm 1 (germyl esters) that are assigned to the C=S vibrations of the monodentate RCS2 ligands (378). The (Ph)3Ge(EtXant) derivatives also show the C=S vibration at 1040 cm 1 (565). Undoubtedly these...
