Description

Under the direction of Dr. Daniel R. Derringer

Three diphosphines, Ph2PCH(H)PPh2 (dppm), Ph2PCH(Me)PPh2 (dppmMe) and Ph2PCH(CN)PPh2 (dppmCN), were prepared using literature procedures. The compounds were characterized by H-1 NMR and IR spectroscopy. Then, in separate studies, two of the phosphines, dppmMe and dppmCN, were combined with a dirhenium compound, Re2(O2CCH3)2Cl4(OH2)2, and refluxed in EtOH for 1 h. The formation of three different diphosphine-containing dirhenium spieces resulted: Re2(O2CCH3)Cl4(dppmCN)2, Re2(O2CCH3)Cl4(dppmMe)2, Re2Cl4(dppmMe)2. These products were characterized by cyclic voltammetry and single-crystal X-ray crystallography.
