Abstract
The synthesis and characterization of 1-(isobutyl)-3-(2.3.5.6 tetramethylbenzyl)-5.6-dimethylbenzimidazolium chloride and its N-functionalized Rhodium(I) N-heterocyclic carbene complex have been described. The ligand 2 and the complex 3 were characterized by IR, 1H NMR and 13C NMR spectroscopy, DART-TOF mass spectrometry and elemental analysis. The coordination mode of the complex was confirmed by single crystal XRD analysis. We performed a comparative theoretical study in order to investigate the impact of the iridium on the optoelectronic and non-linear optical properties of the complex. The M06-2X functional with the mixed basis set (6-31G(d): def2tzvp) was found the best method for optimizing the studied complex since it displayed close geometric data to the experiment. As a novelty in this work, iridium was found to be a performer for NLO applications over rhodium. This Rh(I)- N-Heterocyclic carbenes (NHC) showed good catalytic performance for the hydrosilylation of acetophenone derivatives with triethylsilane at 80 °C for 1 h by using 1 mol % of this complex. The cytotoxic properties of the rhodium(I)–NHC complex have been assessed against MCF7 and MDA-MB-231 cancer cells and the complex show interest activity. The in vitro antibacterial activity of this complex were also investigated against Micrococcus luteus LB 14110, Listeria monocytogenes ATCC 19117, Salmonella Typhimurium ATCC 14028, Staphylococcus aureus ATCC 6538, Pseudomonas aeruginosa and Candida albicans microorganisms indicated their significant biological potential. Additionally, the antioxidant activity of the same complex has been analyzed with DPPH∙ free radical through spectrophotometric method and the result inferred them as an antioxidant. The potential biological activities were investigated by using molecular docking analysis.
