The simualtaneous activation of carbon dioxide and diynes by electrogenerated LNi(0) complexes (L=bpy, pentamethyldiethylenetriamine: PMDTA) enables the selective incorporation of one molecule of CO2 into the unsaturated systems and the preparative-scale
From Stoichiometry to Catalysis: Electroreductive Coupling of Alkynes and Carbon Dioxide with Nickel-Bipyridine Complexes. Magnesium Ions as the Key for Catalysis

The incorporation of carbon dioxide into nonactivated alkynes catalyzed by electrogenerated nickel-bipyridine complexes affords α,β-unsaturated acids in moderate to good yields.The electrocarboxylation reaction was undertaken on a preparative scale in the presence of a sacrificial magnesium anode: the formation of acids from alkynes is stoichiometric with respect to the nickel complex if performed in a two-compartment cell but can be made catalytic in a single-compartment cell.An intermediate nickelacycle was isolated from the reaction with 4-octyne.The cleavage ofthis metallacycle by magnesium ions is the key step to explain catalysis.
Electrogenerated nickel(0) catalyzed carbon dioxide incorporation into α,ω-diynes
Derien, S.,Dunach, E.,Perichon, J.
, p. C43 - C46 (2007/10/02)
Electrogenerated low-valent nickel complexes are active catalysts for carbon dioxide incorporation into α,ω-diynes.A strong influence of the nature of the ligand on the selectivity of this carboxylation has been observed.
