β-二酮亚胺基镍（I）配合物K-2[（LNiI）-Ni-tBu（N-2（2-））（NiLtBu）-L-I]与CO2通过还原偶联反应生成含CO和CO 32的产物，而在使用Ni-I前体[（LNiI）-Ni-tBu（N-2）（NiLtBu）-L-I]后观察到CO2的还原偶联，得到草酸桥连的二镍（II）配合物。向所形成的碳酸盐和草酸盐化合物中添加KC 8导致初始Ni-I络合物在N-2气氛中再生，从而关闭合成循环。
The beta-diketiminato nickel(I) complex K-2[(LNiI)-Ni-tBu(N-2(2-))(NiLtBu)-L-I] reacts with CO2 via reductive disproportionation to form CO and CO32- containing products, whereas after employment of the Ni-I precursor [(LNiI)-Ni-tBu(N-2)(NiLtBu)-L-I] reductive coupling of CO2 was observed giving an oxalate bridged dinickel(II) complex. The addition of KC8 to the carbonate and oxalate compounds formed leads to the regeneration of the initial Ni-I complexes in an N-2 atmosphere, thus closing synthetic cycles.
