  Rational synthesis of tricobalt-molybdenum and -tungsten butterfly clusters with alkyne ligands

  摘要：

  The heterometallic alkyne complexes [CoM(mu-R(1)Cequivalent toCR(2))(CO)(5)Cp] (M = Mo, W; R-1 = R-2 = CO2Me, CO2Et; R-1 = H, R-2 = CO2Me) react with dicobalt octacarbonyl in refluxing toluene to give the 60-electron tetranuclear clusters [Co3M(mu(4)-(RC2R2)-C-1 2)(CO)(9)Cp] in moderate to good yields. The clusters consist of a butterfly-type metal core in which the molybdenum (or tungsten) atom occupies a wing-tip position, as shown by X-ray analysis of three of the complexes.

  cobaltacyclopentadiene complexes, derived from cobalt carbonyl and two alkyne molecules and long believed to be intermediates in cyclotrimerization as well as in the formation of the (three-alkyne-derived) “flyover” complexes, can be isolated in selected cases if the mono(alkyne)−Co2(CO)6 complexes are treated at room temperature with just 1 equiv of alkyne in the presence of trimethylamine N-oxide. The complex (PhCCHCMeCMe)Co2(CO)5

  我们已经表明，在某些情况下，可以分离出衍生自羰基钴和两个炔烃分子的钴环戊二烯络合物，人们长期以来认为它们是环三聚化以及（三炔烃衍生的）“立交”络合物形成中的中间体。在三甲胺N-氧化物存在下，仅用1当量的炔在室温下处理单（炔）-Co 2（CO）6络合物。配合物（PhC CHCMe CMe）Co 2（CO）5已通过X射线晶体学表征。

• A comparison of the reactions of PPh2CH2SR (R = Me, Ph) with alkyne-bridged dicobalt carbonyl complexes and with an iron dicobalt μ3-thioxo carbonyl complex

  The reactions of Ph(2)PCH(2)SR (R = Me, Ph) in toluene with the dicobalt complexes [Co-2(mu-R(1)CCR(2))(CO)(6)] (R(1) = R(2) = CO(2)Me and R(1) = H, R(2) = CO(2)Me) give the monosubstituted complexes [Co-2(mu-R(1)CCR(2))(CO)(5)PPh(2)CH(2)SMe] 1 and [CO2(mu-R(1)CCR(2))(CO)(5)PPh(2)CH(2)SPh] 2. On heating 1 and 2 in toluene solution, loss of CO leads to the bridged species [Co-2(mu-R(1)CCR(2))(mu-PPh(2)CH(2)SMe)(CO)(4)] 3 and [Co-2(mu-R(1)CCR(2))(mu-PPh(2)CH(2)SPh)(CO)(4)] 4. This transformation is readily reversed by treatment of 3 and 4 with CO, showing the Co-S bond in these complexes to be relatively weak. Similar reactions of Ph(2)PCH(2)SR (R = Me, Ph) with [Co2Fe(mu(3)-S)(CO)(9)], however, give only the ligand bridged species [Co2Fe(mu(3)-S)(mu-Ph(2)PCH(2)SR)(Co)(7)] (R = Me 5 and R = Ph 6). Treatment of 5 and 6 with CO causes cleavage of the Co-S bond but, in contrast to 3 and 4, the ligand bridged species readily reform when the CO purge ceases. The structures of 3a and 6 have been confirmed by single-crystal X-ray analysis.
