On July 11, 2022, Falconnet, Alban; Arndt, Jan-Dirk; Hashmi, A. Stephen K.; Schaub, Thomas published an article.Safety of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Triflic-Acid-Catalyzed Friedel-Crafts Reaction for the Synthesis of Diaryl Sulfones. And the article contained the following:
The Friedel-Crafts sulfonylation for the synthesis of diaryl sulfones derivatives was achieved by using triflic acid (TfOH) as the acidic catalyst with aryl sulfonyl chlorides and arenes at elevated temperatures Different sulfones could be synthesized with this method in good to excellent yield and with high selectivity. In contrast to the previous methodol. reported for this sulfonylation, the catalyst and the excess of arene could be easily recovered and re-used in further batches. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Safety of 4,4′-Sulfonylbis(chlorobenzene)
