在2与某些硅烷基炔的反应中，通过（炔）C → Si键断裂和氢转移，形成了一种特殊的Co2配合物，如1，其钴环单元由一个平面的CoC 4和一个折叠的C5环构成.插入的炔到的M C键的特点与Fischer或Schrock卡宾配合物的反应没有观察到与2;其中包含一个cycloalkenylidene配体。
Unusual Co 2 complexes like 1 with a cobaltabicyclic unit constructed from a planar CoC 4 and a folded C 5 ring are formed in the reaction of 2 with certain silylalkynes by (alkyne) C Si bond cleavage and a hydrogen shift. The insertion of the alkynes into the M C bond characteristic of reactions with Fischer or Schrock carbene complexes is not observed with 2; which contains a cyclopentadienylidene ligand.
