The bidentate phosphine ligands 1,2-bis(diphenylphosphino)ethane (dppe), 1,2-bis(diphenylphosphino)ethene (dppee) or 1,2-bis(diphenylphosphino)benzene (dppbe) undergo reactions with the rhenium(V)-imido complex, trans-Re(NPh)Cl3(PPh3)2, in refluxing alcoholic solvent to give mixtures of fac-Re(NPh)Cl3(L-L) and trans-[Re(NPh)X(L-L)2]2+. Mild reaction conditions favor the monosubstituted complexes and harsh conditions favor the salts. The electrochemical properties of the salts reveal subtle differences associated with the backbone of the ligands. The structure of the hydroxy-imido salt trans-[Re(NPh) (OH) (dppbe)2] (ClO4)2?2H2O was determined and shows the rhenium atom displaced 0.536(2) A above the P4 equatorial plane, the largest displacement observed for rhenium(V) compounds containing pi-donor ligands, and the Re-N(imido) distance of 1.757(10) A is the longest observed for rhenium(V)-imido compounds.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13991-08-7 is helpful to your research., Related Products of 13991-08-7
