Zeng, Linwei published the artcilePhoto-induced synthesis of β-sulfonyl imides from carboxylic acids, Formula: C9H8O4, the publication is Chemical Communications (Cambridge, United Kingdom) (2021), 57(55), 6792-6795, database is CAplus and MEDLINE.
A photo-induced imidation process of carboxylic acids is described. Numerous carboxylic acids could convert to β-sulfonyl imides in the presence of N-sulfonyl ynamides under visible light irradiation Control experiments and mechanistic studies demonstrate that this imidation process involves a hydroacyloxylation/radical rearrangement cascade. This protocol represents a direct imidation method from carboxylic acids under mild conditions, with broad scope and high atom-economy.
