A kinetic and mechanistic study on the ligand substitution reaction between polymer-supported RuCl3NO(SbPh3)2 and PPh3 is reported.Three resins with different Sb and Ru contents have been employed, and a comparison with the homogeneous reaction of the RuCl3NO chelate complex has been made.The results indicate that the reaction involves two different pathways starting from a common intermediate.Further evidence for the strong tendency to chelation of the Ru complex in the anchoring reaction is found.
