We report herein a mild and catalytic intramolecular aminofluorination of unactivated alkenes. Thus, with the catalysis of AgNO3, the reactions of various N-arylpent-4-enamides with Selectfluor reagent in CH2Cl2/H2O led to the efficient synthesis of 5-fluoromethyl-substituted γ-lactams. A mechanism involving silver-catalyzed oxidative generation of amidyl radicals and silver-assisted fluorine ...Palladium, a key transition metal in advancing modern organic synthesis, mediates diverse chemical conversions including many carbon–carbon bond formation reactions between organic compounds.

Mycotoxin is a broad term for the harmful substances produced by molds. Mycotoxins are the most toxic chemical agents found in food and feed, posing the greatest threat to human and animal health. In this context, the contamination of meat by mycotoxin is one of the most pressing concerns to be addressed in terms of food safety [1, 2].
