Three new organoiridium complexes are prepared from (Ir(COD)(μ‐Cl)) 2 and diphosphine in 1:2 molar ratio, and characterized by means of IR, 1 H NMR electric conductivity and elemental analysis. Using acetonitrile as substrate. we investigated the abilities of these complexes to activate sp 3 C‐H bond and promote insertion reaction of CO, CO 2 into metal‐carbon bond. The experimental results show that the activity of (Tr(COD)(diphos))Cl is correlated to the electronic property of diphosphine chelate ligand.
