The ionic complex reacts with Lewis bases (L) to give .Two reaction paths are observed: one involving carbon monoxide insertion followed by attack of the L ligand, and a second in which ligand exchange is followed by an insertion reaction.The relative importance of the two paths depends on the nature and the concentration of L.The neutral complexes also react with Lewis bases to give .When X=I the acetyl complex is readily transformed into the corresponding ionic methyl complex I.The neutral complexes react faster than the ionic ones.The structure of the ionic and neutral complexes has been assigned on the basis of i.r. and n.m.r. evidence.
