摘要: Abstract This paper deals with the synthesis of rhodium(I) Vaska-type complexes general form trans-[Rh(CO)X(PX3)] (X=halide, X aryl or alkyl substituent) when incorporating tertiary phosphine ligands and illustrates their simple application as probes to evaluate steric electronic effects, specifically in ligands, analogous Tolman model. They are easy prepare do not exhibit toxicity corresponding nickel complexes, while structural infrared data can be conveniently utilised estimate ligand properties relative ease. These often obtained by-products reacting [Rh(μ-Cl)(CO)2]2 bidentate non-stoichiometric amounts, thus yielding unreacted dimer, which, upon addition phosphine, quantitatively converts complex. A representative summary systems is reported structures correlated related literature complexes. Selected aspects reactions arsine stibine analogues illustrated solvent effects on equilibrium behaviour well iodomethane oxidative described.
