  Site selectivity studies on homonuclear metal dimer complexes: Substitution reactions of Re2(CO)9L

  摘要：

  The reaction of Re2(CO)9L (L = tBuNC, P(O-o-tol)3, P(CH2C6H5)3, R'CN, R' = Me, Et, Pr, Ph) with L'(L' = tBuNC, R'CN) in the presence of PdO or Me3NO yields the 2,3-, 2,6- or 1,6-isomers of Re2(CO)8LL'. The PdO reactions give only the 2,6-isomer while the Me3NO induced reactions give statistical mixtures of the 2,6- and 2,3-isomers when L = L' = R'CN. When L = tBuNC and L' = R'CN higher ratios (approximately 5:1) of 2,6- and 2,3-isomers are observed. The product isomer ratios from the reaction of Re2(CO)9L and L' were found to be different from those from the reaction of the mixtures of Re2(CO)5I/Re(CO)4LI with L'. The substitution chemistry of the Re(CO)5Re(CO)4L dimer is thus not predictable from the chemistry of the monomer fragments. All the new dimer products have been characterised by IR and NMR (H-1, C-13, P-31) spectroscopy.
