摘要

Many oxidation reactions can be hazardous when run on large scale. The manufacturing process for the production of R411, a developmental compound indicated for the treatment of asthma, includes the oxidation of 2-chloro-6-methylbenzaldehyde to the corresponding carboxylic acid. The use of sodium chlorite in this transformation was efficient and economical, but there were safety concerns regarding the use of hydrogen peroxide to ...
