We have investigated the reactivities of a series of dinuclear iridium(II,II) and rhodium(II,II) 1,3‐butadiene‐1,4‐diyl complexes derived from two types of alkyne‐containing ligands. Newly developed ligand 2 afforded 2nd generation diiridium complexes that have higher reactivity toward halide substitution and acetylide formation. The significant differences in reactivity, influenced by the 1,3‐butadiene‐1,4‐diyl ligand backbone of these complexes, have been systematically investigated by synthetic studies as well as X‐ray crystallographic and spectroscopic analyses.
