Description
Dirhenium(II) complexes that contain two bridging Ph2PCH2PPh2 (dppm) ligands are known to adopt one of three possible configurations. Characterization of these complexes by H-1 NMR spectroscopy has revealed that the chemical shifts of certain hydrogen atom are configuration dependent. To our knowledge, no one has explained this dependence. Here we summarize our efforts to put an explanation within our reach. To get to this point, a complex of the type cis-Re2(O2CCH3)2X2(dppmR)2 (where X is Cl or Br and R is CN or CH3), must be synthesized, we believe. This report details our accomplishments this year. It includes a summary of the reactions that were carried out and the characterizations (by cyclic voltammetry and IR and NMR spectroscopy) that were done.
