Electrocatalytic dimerisation of non-heteroatom-substituted manganese alkynylcarbene complexes†
Abstract
Upon controlled potential electrolysis (−1.30 V vs. C(R)C
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[η4-(E)-RC
