Electrocatalytic dimerisation of non-heteroatom-substituted manganese alkynylcarbene complexes.
Upon controlled potential electrolysis (-1.30 V vs. SCE), the alkynylcarbene complexes MeCp(CO)2Mn=C(R)C [triple bond]CR' are seen to undergo an electrocatalytic dimerisation by coupling of the remote alkynyl carbon atoms to afford the ene-diyne dimanganese complexes [MeCp(CO)2Mn]2[eta 4-(E)-RC [triple bond] C(R')C=C(R')C [triple bond] CR].
