Abstract

Reaction of the mixed-metal alkyne-bridged complexes [(η⁵-C₅H₅)(OC)₂M{μ-C ₂(CO₂Me)₂}Co(CO)₃] (M=Mo or W) with Ph₂PCC^tBu in refluxing toluene gives the complexes [(η⁵-C₅H₅)(OC)₂M{μ- ^tBuCCC(CO₂Me)=C(CO₂Me)PPh ₂}Co(CO)₂], [(η⁵-C₅H₅)(OC)₂M{μ-C ₂(CO₂Me)₂}Co(CO)₂(Ph ₂PCC^tBu)] (M=Mo or W) and [(η⁵-C₅H₅)(OC)W{μ-C(CO ₂Me)=C(CO₂Me)CC^tBu}(μ-PPh ₂)Co(CO)₂]_. The structures of the two complexes, [(η⁵-C₅H₅)(OC)₂Mo{μ- ^tBuCCC(CO₂Me)=C(CO₂Me)PPh ₂}Co(CO)₂] and [(η⁵-C₅H₅)(OC)W{μ-C(CO ₂Me)=C(CO₂Me)CC^tBu}(μ-PPh ₂)Co(CO)₂], have been determined by X-ray analysis. Possible reaction pathways for the formation of the new complexes are proposed and discussed.
