  Formation of Arenes and of Tetracarbonyl(hexatrienediyl)dicobalt (“Flyover”) Complexes from Co₂(CO)₈

  摘要：

  The cobalt carbonyl mediated cyclotrimerization of alkynes to yield both arenes and "flyover" complexes (which contain a C6Co2 ring) has been reexamined with particular regard to the intermediacy of cobaltacyclopentadienes. Since the latter can now be obtained in controlled fashion from (alkyne)Co-2(CO)(6) and can react with a third alkyne under mild conditions by using trimethylamine-N-oxide as promoter, the incorporation of three different alkynes into both arenes and flyovers has become possible. Cobaltacyclopentadienes, like their precursors, catalyze alkyne cyclotrimerization, but flyovers do not do so under comparable conditions and hence are not on the main reaction path to arenes. In some circumstances cleavage of cobaltacyclopentadienes must occur to account for the observed arene products. Crystal structures of two flyover complexes are reported.

  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。
