NaBrO/guanidinium-based sulfonic acid: as a transition metal- and strong inorganic acid-free oxidation system for alcohols and alkyl arenes

The bromate anion as a safe, cheap, stable and easily stored oxidizing system has been utilized for the oxidation of a wide range of alcohols and alkyl arenes to the corresponding aldehydes and ketones. The reaction was performed in the presence of guanidinium-based sulfonic acid as a Brønsted acid...

Description
Summary:The bromate anion as a safe, cheap, stable and easily stored oxidizing system has been utilized for the oxidation of a wide range of alcohols and alkyl arenes to the corresponding aldehydes and ketones. The reaction was performed in the presence of guanidinium-based sulfonic acid as a Brønsted acid organocatalyst in aqueous acetonitrile at room temperature. Products are isolated in high yields and the catalyst could be easily recovered and recycled. A new catalytic system for the oxidation of organic compounds in good to excellent yields at room temperature.
