  摘要：

  The oxidation of two triscarbonyl fac-(L-spectator)Re-I(CO)(3)(L-acceptor)(z) complexes (L-spectator = 4,4'-bpy; L-acceptor = dipyridyl[3,2-a:2'3'-c] phenazine (dppz) and z = + or L-spectator = Cl-; L-acceptor = bathocuproinedisulfonate (bcds(2-)) and z = 2-) by azidyl radicals, N-3(.), was investigated by pulse radiolysis. Reaction rate constants were determined for the electron transfer reactions between the Re(II) products and reductants, Ru(bipy)(3)(3+) and Ni(Me-6-[14]dieneN(4))(2+), and used for the calculation of the self-exchange rate constant of the Re(II)/Re(I) couples. The self-exchange rate constants, k similar to 10(7) M-1 s(-1), were one order of magnitude larger than the constant, k similar to 10(6) M-1 s(-1), communicated in the literature for the [Re(DMPE)(3)](+/2+) (DMPE = 1,2-bis(dimethylphosphine)ethane). The larger rate constants of the triscarbonyl complexes are in agreement with the smaller inner sphere reorganization energy of the complexes relative to [Re(DMPE)(3)](+/2+). Moreover, the study demonstrated that the redox potential of the azidyl radicals is E-N3(/N3).(-0) = 1.70 V versus NHE, a value larger than one communicated earlier, and that the self-exchange rate constant of the N-3(.)/N-3(-) couple is k(N3)(/N3)(.)(-) = 2.7 x 10(6) M-1 s(-1). The small value of the N-3(.)/N-3(-) self-exchange rate constant has been related to the large solvent reorganization energy of the reaction. (C) 2007 Elsevier B.V. All rights reserved.
