Relevant articles and documents

Biomimetic synthesis of symmetric acyclic diketones

A convenient synthetic method for the preparation of symmetric acyclic diketones from dicarboxylic acids is provided. Three bis-benzimidazolium salts were used as tetrahydrofolate coenzyme model, thus the biomimetic synthesis of three symmetric acyclic diketones was successfully accomplished by using the addition-hydrolysis reaction of corresponding bis-benzimidazolium salts with methyl magnesium iodide.

Process for producing a higher carbonyl compound

An industrially suitable process for producing a higher carbonyl compound by the oxidation of an olefinic compound having at least six carbon atoms is provided. Said improved process comprises oxidizing the olefinic compound in aqueous medium containing palladium or salt thereof and a copper salt in the presence of a specific water-soluble polyoxyalkylene compound in an amount of from about 1/4 to about 3 parts by weight per 1 part by weight of water contained in the reaction mixture. The improvement is demonstrated in terms of yield, selectivity, separation of the product, and recycle of the catalyst.
