“…Synthesis of our new suite of heterobimetallic complexes was undertaken using the "transition metal first" strategy commonly exploited in our laboratory. 42,44 Vaska's complex, [Ir(PPh 3 ) 2 (CO)Cl] (1a) or its rhodium congener, [Rh(PPh 3 ) 2 (CO)Cl] (1b, NOTE: all complexes denoted "a" contain Ir and complexes denoted "b" contain Rh), were first reacted with a silver salt in the presence of the desired pyridinemethanol (Scheme 1), hydroxypyridine (Scheme 2), or hydroxyquinoline bridging ligand (Scheme 3) resulting in complexes 8a-17b. Monometallic precursors were then reacted with triisobutylaluminum to generate the desired bimetallics 18a-21b (Scheme 4).…”
