      Synthesis, structure and density functional theory (DFT) studies of a series of new ruthenium complexes, [1-(R)-3-𝑁-(benzylacetamido)imidazol-2-ylidene]RuCl(𝑝-cymene) [R = Me (1c), 𝑖-Pr (2c), CH2Ph (3c); 𝑝-cymene = 4-𝑖-propyltoluene] supported over $N/O$-functionalized N-heterocyclic carbene (NHC) ligands are reported. In particular, the ruthenium (1-3)c complexes were synthesized from the respective silver complexes, [1-(R)-3-𝑁-(benzylacetamido)imidazol-2-ylidene]2Ag+Cl− [R = Me (1b), 𝑖-Pr (2b), CH2Ph (3b)] by the treatment with [Ru(𝑝-cymene)Cl2]2 in 65-76% yields. The molecular structures of (1-3)c revealed the chelation of the N-heterocylic carbene ligand through the carbene center and an amido sidearm of the ligand in all of the three complexes. The density functional theory studies on the ruthenium (1-3)c complexes indicated strong binding of the NHC ligand to the metal center as was observed from the deeply buried NHC-Ru 𝜎-bonding molecular orbitals.
