dc.description.abstract | Complexes [Pd{(S)-NHCMes,R}2] (R = Me, 2a; iPr, 2b; iBu, 2c) and [Pd{(R)-NHCMes,Me}2] (2a’) were prepared by
reaction of the corresponding imidazolium precursor [ImMes,R] (namely (S)–2-alkyl(3-mesityl-1H-imidazol-3-
ium-1-yl)acetate, 1a-c, and (R)-2-methyl(3-mesityl-1H-imidazol-3-ium-1-yl)acetate, 1a’), with Ag2O and sub-
sequent interaction with Pd(OAc)2, under appropriate conditions. Alternatively, complexes 2 were also obtained
by treating compounds [ImMes,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 = η5-C5H5) with [ImMes,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, 1H
and 13C 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 κ2-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. | es |
