  silver(I)-mediated decarboxylative fluorination of paraconic acids using Selectfluor® as a fluorine source is reported. Readily available paraconic acids undergo decarboxylative fluorination with Selectfluor® mediated by AgNO3 to give the corresponding β-fluorinated γ-butyrolactones in moderate to good yields. This approach serves as a direct and site-selective strategy for the introduction of a fluorine atom at

  Decarboxylative transformations of paraconic acids, a class of γ-butyrolactones containing a carboxylic acid group at the β-position as their characteristic functionality, by using a combination of AgNO3/K2S2O8 were investigated. The dual function of AgNO3 as an initiator of the decarboxylation process and as a source of nitrogen dioxide radicals that react with aliphatic carboxylic substrates is reported
