Alternatively, complexes 2 were also obtained by treating compounds [Im(Mes,R)], 1, with an in-situ prepared lithium diisopropylamide solution and then reaction with [Pd(OAc)(2)]. On the other hand, the nickel complex [Ni{(S)-NHCMes,iPr}(2)], 3b, was synthesized by the interaction of the complex [NiCp2] (Cp = eta(5)-C5H5) with [Im(Mes,iPr)], 1b, in THF. If this reaction was carried out in acetonitrile, a mixture of complex 3b and the cyclopentadienyl monocarbene complex [NiCp{(S)-NHCMes,iPr}], 4b, was obtained. Similarly to 2b, compound 3b was also prepared by the in-situ formation of the carbene [(S)- NHCMes,iPr](-) and then reaction with [NiBr2(dme)] (dme = 1,2-dimethoxyethane). Complexes 2, 3 and 4 were obtained with good yields and fully characterized by analytical (HR-ESI and microanalysis), spectroscopic (IR, H-1 and C-13 NMR and polarimetry) and X-ray methods (2c). In the solid state, 2c is a square planar complex con-taining two [(S)-NHCMes,iBu](-) ligands coordinated in a kappa(2)-C,O fashion, where the carbene and carboxylate donors have the expected trans configuration. The existence of two possible conformers of complexes 2 and 3 was analyzed using DFT methods.Ministerio de Ciencia e InnovaciónUniversidad de AlcaláComunidad de MadridJunta de AndalucíaEuropean Social FundElsevier20222022-06-01journal articlehttp://purl.org/coar/resource_type/c_6501NAhttp://purl.org/coar/version/c_be7fb7dd8ff6fe43info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10017/66892https://dx.doi.org/10.1016/j.ica.2022.120946reponame:e_Buah Biblioteca Digital Universidad de Alcaláinstname:Universidad de Alcalá (UAH)InglésengMCIN Not available PGC2018-093443-B-I00MCIN Not available PID2020-114637GB-I00Comunidad de Madrid http://dx.doi.org/10.13039/100012818 Not available EPU-INV%2F2020open accesshttp://purl.org/coar/access_right/c_abf2Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessoai:ebuah.uah.es:10017/668922026-06-18T11:13:07Z
