Structural Diversity in Cyclometalated Diiridium(III) Complexes with Bridging syn and anti μ2‐Oxamidato and μ2‐Dithioxamidato Ligands

“…Complex 3 d . Following the procedure for complex 3 b , the following reagents were used: sodium methoxide (61 mg, 2.6 eq), N,N’ ‐bis(4‐fluorophenyl)oxalamide [43] (158 mg, 1.3 eq) in methanol (10 mL) and dichloro‐dimer (500 mg, 0.44 mmol, 1 eq) in THF (45 mL) was added. The reaction mixture was stirred at r.t for 24 h. The solvent was removed and the crude product was dissolved in DCM (100 mL).…”

“…The crude product was purified by column chromatography over silica gel, eluting sequentially with DCM:hexane (2 : 1 v/v), DCM:hexane (5 : 1 v/v) then DCM (saturated with K 2 CO 3 and 2 % Et 3 N) to give complex 3 c (130 mg, 62 %). Complex 3 d. Following the procedure for complex 3 b, the following reagents were used: sodium methoxide (61 mg, 2.6 eq), N,N'-bis(4-fluorophenyl)oxalamide [43] (158 mg, 1.3 eq) in methanol (10 mL) and dichloro-dimer (500 mg, 0.44 mmol, 1 eq) in THF (45 mL) was added.
