    those obtained by density functional theory (DFT) calculations. Activation parameters obtained by experiments as well as a systematic DFT study supported the fact that reactions occurred through slightly distorted quadrangular pentacoordinated σ-bond metatheses, in which the Cl atom underwent a more indirect course than the Br atom. Moreover, exchange reactions were employed as the accessible prototype

    reactions of tertiary phosphine complexes of Pd(II) with phosphine !igand: have been investigated by NMR and conductivity measurements. Depending on the nature of the phosphine ligand either ligand exchange or the formation of cationic complexes can occur. Relative equilibrium constants for these reactions have been obtained. NMR line broadening experiments have enabled the relative rates of ligand exchange
