ruthenium 1 1 bis diphenylphosphino ferrocene catalysed Oppenauer Oxidation of alcohols and lactonisation of alpha omega diols using methyl isobutyl ketone as oxidant
Advanced Synthesis & Catalysis, 2013Co-Authors: Celine M Nicklaus, Pim Huat Phua, Teddy Buntara, Sebastien Noel, Hero J Heeres, Johannes G De VriesAbstract:A number of ruthenium catalysts, made in situ from [Ru(p-cymene)Cl-2](2) and various monodentate and bidentate phosphorus ligands were screened in the double Oppenauer Oxidation of 1,6-hexanediol to caprolactone using methyl isobutyl ketone as oxidant and potassium carbonate as base. The catalyst based on 1,1-bis(diphenylphosphinyl)ferrocene gave this lactone in excellent yield. The same catalyst was evaluated for the Oxidation of other diols to their lactones, of primary alcohols to the corresponding aldehydes and of secondary alcohols to the ketones under the same reaction conditions. The products were obtained in moderate to excellent yields.

Magnesium salt promoted tandem nucleophilic addition-Oppenauer Oxidation of aldehydes with organozinc reagents.
Organic & biomolecular chemistry, 2016Co-Authors: Xing Ling Zhao, Hulmet Hügel, Danfeng Huang, Ke-hu WangAbstract:A magnesium salt promoted synthesis of ketones via tandem nucleophilic addition-Oppenauer Oxidation of aldehydes using organozinc chemistry was demonstrated. Magnesium salts concomitantly generated via magnesium metal mediated organohalide zincation exhibit high efficacy for nucleophilic addition of organozinc reagents to aromatic aldehydes and thereafter Oppenauer Oxidation whereby ketones are formed in high to excellent yields.

tandem nucleophilic addition Oppenauer Oxidation of aromatic aldehydes to aryl ketones with triorganoaluminium reagents
Organic and Biomolecular Chemistry, 2013Co-Authors: Yanshou Yang, Ke-hu Wang, Helmut M Hugel, Danfeng HuangAbstract:In the presence of pinacolone, the in situ prepared triorganoaluminium reagents reacted with aromatic aldehydes to give ketones in moderate to high yield. We propose that the products are formed via a tandem organoaluminium reagents addition-Oppenauer Oxidation sequence.
