Abstract
The coordination of an additional [CP(CO)(2)Mn] fragment to the alkyne link age of an alkynylcarbene complex of the type CP(CO)(2)Mn-C(R')C=CR" yields a highly fluxional molecule, in which the [eta (1)-carbene] and [eta (2)-al kyne] moieties are seen to exchange rapidly on the NMR time scale.
