The stereoelectronic parameters of the π-annulated carbene 1,3-di-iso-propylbenzimidazolin-2-ylidene (BIiPr) were evaluated in this study. N-iso-propyl substituents and additional π-backbone BIiPr lead to a moderate steric bulk, which lies between that backbone unsubstituted IiPr its methylated congener IiPrMe (IR = 1,3-diorganylimidazolin-2-ylidene; IRMe 1,3-diorganyl-4,5-dimethylimidazolin-2-ylidene). While net electron donation properties are slightly lower than those IiPrMe, π-acidity is significantly higher imidazole-based NHCs cAACs. These unique led distinctly different reactivities with Ni(0) reagents comparison IiPrMe. reaction [Ni(COD)2] afforded homoleptic three-coordinated [Ni(BIiPr)3] (1) olefin complex [Ni2(BIiPr)4(μ2-(η2:η2)-COD)] (2) only as side product. [Ni(CO)4] yielded [Ni(BIiPr)2(CO)2] (3), was employed starting material for facile synthesis uncapped, NHC-ligated nickel Chini-cluster analog [Ni3(BIiPr)3(μ2-CO)3] (4). This cluster synthesized from 3 [Ni(COD)2]. results demonstrate reveal influence small variations substitutional pattern on stabilities transition metal complexes.
