Abstract

The coordination of an additional [Cp(CO)₂Mn] fragment to the alkyne linkage of an alkynylcarbene complex of the type Cp(CO)₂Mn [double bond, length half m-dash] C(R′)C [triple bond, length half m-dash] CR″ yields a highly fluxional molecule, in which the [η¹-carbene] and [η²-alkyne] moieties are seen to exchange rapidly on the NMR time scale.
