Biological assays and theoretical density functional theory calculations of Rh(I), Ir(III), and Ru(II) complexes of chiral phosphinite ligand

Four metal complexes, IL‐OPPh 2 ‐Ru‐ p ‐cymene (3) , IL‐OPPh 2 ‐Ru‐benzene (4) , IL‐OPPh 2 ‐Ir‐Cp* (5) , IL‐OPPh 2 ‐Rh‐COD (6) , have been evaluated for in vitro antioxidant activity such as 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging and reducing power activity. Maximum scavenging activity (71.43%) was obtained with IL‐OPPh 2 ‐Ru‐ p ‐cymene, whereas IL‐OPPh 2 ‐Rh‐COD showed the highest reducing power ability. The complexes were also...
