Equilibrium constants and rates have been determined for the isomerization of the linkage isomers (OC)5W[κ1-PPh2CH2P(p-tolyl)2] (5) and (OC)5W[κ1-P(p-tolyl)2CH2PPh2] (6). It is proposed that this intramolecular exchange involves a nucleophilic attack of the pendant phosphine on a cis carbonyl group, followed by ring opening and a 1,2-shift.
