Direct oxidation of alcohols to carboxylic acids over ruthenium hydride catalyst with diphenyl sulfoxide oxidant

In the present work, a new method for the synthesis of carboxylic acids over ruthenium hydride catalyst is reported. Direct oxidation of alcohols to their corresponding carboxylic acids with diphenyl sulfoxide oxidant over RuHCl(CO)(PPh3)3 catalyst was investigated. Mild reaction conditions, short reaction times and excellent yields make this method as an appealing way for preparation of carboxylic acids.

A new and efficient method for the direct oxidation of alcohols to their corresponding carboxylic acids with diphenyl sulfoxide as oxidant in the presence of catalytic amounts of RuHCl(CO)(PPh3)3 is reported. Mild reaction conditions, short reaction times and excellent yields are the advantages of the present work.Figure optionsDownload as PowerPoint slideHighlights
