Multiple bonds between main group elements and transition metals, 154 methylrhenium(V) oxo complexes: Derivatives of di(4-t-butylpyridine) dichloromethyloxorhenium(V)

Article abstract of DOI:10.1016/0022-328X(95)05928-I

Di(4-t-butylpyridine)dichloromethyloxorhenium(V) (1) is obtained by reductive halogenation of methyltrioxorhenium(VII) in the presence of t-butylpyridine. A number of new methylrhenium(V) complexes can be synthesized by substitution of the halide and/or pyridine ligands, e.g. with chelating N-and P-bases or Schiff base ligands. The new rhenium complexes exhibit an asymmetric coordination of the ligands.
