Yu, Zhiqun published the artcileBronsted acid-catalyzed chlorination of aromatic carboxylic acids, Product Details of C7H13NO2, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (2021), 196(8), 685-689, database is CAplus.
The chlorination of aromatic carboxylic acids with SOCl2 has been effectively performed by reacting with a Bronsted acid as the catalyst. Based on this discovery, an efficient catalytic method that is cheaper than traditional catalytic methods was developed. 20 substrates were chlorinated offering excellent yields in a short reaction time. And the SOCl2/Bronsted acid system has been used in a larger scale preparative reaction. A dual activation mechanism was proposed to prove the irreplaceable system of SOCl2/Bronsted acid.
