Kinetic studies of CO substitution of metal carbonyl in the presence of O-atom transfer reagents show the reaction are an associative mechanism,where a carbonyl carbon atom is attacked by the O-atom of the reagent,affording the good leaving group CO 2 and generating an active intermediate which readily reacts with the entering ligand to produce the substituted product. In this pepar,result and dissovery of the studies are summarized systematically.Various factors that affect the rates of CO substitution are discussed in detail.
