Abstract

The reaction between the ethylidyne-substituted cluster MeCCo2MoCp(CO)8 (1) and the diphosphine ligand 2,3-bis(diphenylphosphino)maleic anhydride (bma) in refluxing CH2Cl2 has been investigated and found to afford the new mixed-metal clusters MeCCo2MoCp(CO)6[trans-2,3-bis(diphenylphosphino)succinic anhydride] (2) and Co2MoCp(CO)5[μ-C(Me)C=C(PPh2)C(O)OC(O)](μ-PPh2) (3), with the latter cluster representing the principal reaction product. Refluxing 1 with bma in either 1,2-dichloroethane or toluene yields only 3. The tetrahedrane cluster PhCCo2Mo(η5-C5H4CHO)(CO)8 (4), which contains a formyl-substituted cyclopentadienyl ring, has also been examined with added bma in refluxing CH2Cl2 and found to give only Co2Mo(η5-C5H4CHO)(CO)5[μ-C(Ph)C=C(PPh2)C(O)OC(O)](μ-PPh2) (5). All three products have been isolated and characterized spectroscopically in solution, and each molecular structure has been determined by X-ray crystallography. Cluster 2 contains a bridging diphosphine ligand with a succinic anhydride ring that results from the formal reduction of the maleic anhydride platform of the bma ligand, while clusters 3 and 5 each exhibit triangular Co2Mo cores, whose one face is capped by a 6e- C(R)C=C(PPh2)C(O)OC(O) [where R = Me (3), Ph (5)] ligand. The observed substitution products are discussed as a function of the capping carbyne group, ancillary polyene ligand, and related derivatives prepared by our groups.

Graphical Abstract

Thermolysis of the mixed-metal cluster MeCCo2MoCp(CO)8 (1) with bma in CH2Cl2 furnishes the new clusters MeCCo2MoCp(CO)6[trans-2,3-bis(diphenylphosphino)succinic anhydride] (2) and Co2MoCp(CO)5[μ-C(Me)C=C(PPh2)C(O)OC(O)](μ-PPh2) (3) as the minor and major products, respectively. The reaction between bma and the related benzylidyne-capped cluster PhCCo2Mo(η5-C5H4CHO)(CO)8 (4), which contains a formyl-substituted cyclopentadienyl ring, has also been examined and found to afford only Co2Mo(η5-C5H4CHO)(CO)5[μ-C(Ph)C=C(PPh2)C(O)OC(O)](μ-PPh2) (5) in moderate yield.
