Reaction Conditions:

with C₃₀H₃₈Cl₂Ir₂N₄ in dimethyl sulfoxide at 30; for 4.5 h;

Steps:

2 Example 2: Dinuclear and half-filled ruthenium complexes containing bisimine ligands catalyze the oxidation of halogenated hydrocarbons to aldehydes

The catalyst prepared in Example 1 was used to catalyze the oxidation of a halogenated hydrocarbon:To a solution of dinuclear and half-filled ruthenium complex (0.001 mmol, 0.9 mg) in DMSO, was added to ethyl bromide (1 mmol, 109 mg).Open reaction, reaction temperature 30 ° C, reaction time is 270 minutes,After the reaction, the reaction solution is washed with water, extracted and concentrated.The crude product is separated by silica gel column chromatography and dried to a constant mass.The corresponding aldehyde compound C2H4O (41 mg, yield 93%) was obtained.
