Unusual reactions of cationic carbyne complexes of manganese and rhenium with the carbonylmetal anions [Ir(CO)4]- and [Ru(CO) 4]2-. Novel route to heteropolymetallic bridging carbyne complexes

The reaction of a cationic carbyne complex of manganese, [(η5-C5H5)(CO)2Mn≡CC 6H5]BBr4 (1), with [(Ph3P) 2N] [Ir(CO)4] (3) in THF at low temperature gives a novel Mn2-Ir2 mixed-tetrametal bridging carbyne complex with μ and μ3 bridging carbyne ligands, [Mn2Ir 2(μ-CC6H5)(μ3-CC 6H5)(μ-CO)3(CO)3(n 5-C5H5)2] (5), and a related Mn 2-Ir2 mixed-tetranuclear cluster with a μ bridging carbene ligand and a μ3 bridging carbyne ligand, [Mn 2Ir2{μ-C(CO)-C6H5} (μ3-CC6H5)(μ-CO)3(CO) 4(η5-C5H5)2] (6). A cationic carbyne complex of rhenium, [(η5-C5H 5)(CO)2Re≡CC6H5]BBr 4 (2), reacts similarly with 3 to afford the corresponding Re 2-Ir2 mixed-tetrametal cluster [Re2Ir 2{μ-C(CO)C6H5}(μ3-CC6H 5)(μ-CO)3(CO)4(η5-C 5H5)2] (8) and a novel Re-Ir2 mixed-trimetal bridging carbyne complex with an allyl ligand, [ReIr 2(μ-η1:η2-C3H 5)(μ3-CC6H5)(μ-CO) 2(CO)4(η5-C5H5)] (7). The cationic carbyne complex 1 also reacts with the anionic compound Na 2[Ru(CO)4] (4) to give a heterotrimetal bridging carbyne complex with a μ-H ligand, [MnRu2-(μ-H)(μ-CO) 2(μ3-CC6H5)(CO) 6(η5-C5H5)] (10), and the manganese aminocarbene complex [(η5-C5H 5)(CO)2Mn=C(C6H5)NH2] (11), while the analogous reaction of the cationic carbyne complex 2 with 4 produces a novel Re2-Ru2 mixed-tetrametal cluster with a μ3-C(CC6H5)(μ-CC6H 5) bridging carbene ligand, [Re2Ru2{μ 3-C(CC6H5)(μ-CC6H 5)}(μ-CO)(CO)8(η5-C5H 5)2] (13), in addition to the corresponding heterotrimetal bridging carbyne complex [ReRu2(μ3-CC 6H5)(μ-H)(μ-CO)2(CO)6(η 5-C5H5)] (12) and aminocarbene complex [η5-C5H5(CO)2Re=C(C 6H5)NH2] (14). The structures of complexes 6, 7, 11, 13, and 14 have been established by X-ray diffraction studies.

Novel reactions of cationic carbyne complexes of manganese and rhenium with polymetal carbonyl anions. An approach to trimetal bridging carbyne complexes

The reaction of a cationic carbyne complex of manganese, [(η-C5H5)(CO)2Mn≡CC6H 5]BBr4 (1), with [(Ph3P)2N]2[Ru3(CO)11] (3) in THF at low temperature gave the heteronuclear trimetal bridging carbyne complex [MnRu2(μ-H)(μ-CO)2(μ3-CC6H 5)(CO)6(η-C5H5)] (7). A cationic carbyne complex of rhenium, [(η-C5H5)(CO)2Re≡CC6H 5]BBr4 (2), reacts similarly with 3, affording the corresponding bridging carbyne complex [ReRu2(μ-H)(μ-CO)2(μ3-CC6H 5)(CO)6(η-C5H5)] (8) and neutral Re-carbyne dimer [Re(CO)2(η-C5H5)(μ-CC6H5 )]2 (9). The compound [(Ph3P)2N]2[Os3(CO)11] (4) only reacts with 1 to give the trimetal bridging carbyne complex [MnOs2(μ-H)(μ-CO)2(μ3-CC6H 5)(CO)6(η-C5H5)] (10) and neutral Mn-carbyne dimer [Mn(CO)2(η-C5H5)(μ-CC6H5 )]2 (11). [(Ph3P)2N]2[Fe4(CO)13] (5) also reacts with cationic carbyne complexes 1 and 2 to give the trimetal bridging carbyne complexes [MnFe2(μ-H)(μ-CO)2(μ3CC6H 5)(CO)6(η-C5H5)] (12) and [ReFe2(μ-H)(μ-CO)2(μ3-CC6H 5)(CO)6(η-C5H5)] (13), respectively. Product 13, when treated with an excess of PPh3, gave the PPh3-substituted bridging carbyne complex [ReFe2(μ-H)(μ-CO)2(μ3-CC6H 5)(CO)5(PPh3)(η-C5H5) ] (14). In contrast to carbonylmetal anions 3-5, [Mo(η-C5H5)2(H)CO][Mn3(CO)9 (μ-SC6H5)4] (6) reacts with 1 to produce not the analogous bridging carbyne complexes but rather the mercapto-carbene complex [(ηC5H5)(CO)2Mn=C(SC6H5 )C6H5] (15) and the thiolato-bridged Mo-Mn carbonyl complex [Mo(η-C5H5)(CO)2(μ-SC6H5 )2Mn(CO)3] (16), while the analogous reaction of 2 with 6 yields the mercaptocarbene complex [(η-C5H5)(CO)2Re=C(SC6H5 )C6H5] (17) and phenylcarbene complex [(η-C5H5)(CO)2Re=C(H)C6H5 ] (18). The structures of 7, 9, 13, 14, and 16 have been established by X-ray diffraction studies.
