The δ in 18 + δ Electron Complexes: Importance of the Metal/Ligand Interface for the Substitutional Reactivity of 'Re(0)' Complexes (α-diimine-)ReI(CO)3(X)

Autor: Axel Klein, and Conny Vogler, Wolfgang Kaim

Publikováno v: Organometallics. 15:236-244

The factors determining the electron transfer-induced halide labilization in complexes (α-diimine)Re(CO)3(Hal), Hal = Cl and Br, were systematically studied via EPR and cyclic voltammetry in the presence of substituting ligands such as triphenylphos
