industries, general and site-specific C(sp(3))-F bond formations are still a challenging task. We report here that with the catalysis of AgNO(3), various aliphaticcarboxylicacids undergo efficient decarboxylative fluorination with SELECTFLUOR(®) reagent in aqueous solution, leading to the synthesis of the corresponding alkyl fluorides in satisfactory yields under mild conditions. This radical fluorination

The Substituted Amine Analogs (SAA) derivative compounds and SAA complex compounds disclosed in the present invention are characterized as compositions having the functions of inhibiting disorders caused by oxidative stress, and more particularly to those SAA derivative compounds capable of inhibiting disorders caused by oxidative stress because of neurodegenerative diseases, lung diseases, oxidative stress-induced heart disease and carvenosus dysfunction.
by the treatment of Cu2O with HF. After calcination at 100 °C or higher temperature, this compound was successfully used as a highly effective halogen-exchange fluorination reagent for primary alkylhalides in the presence of pyridine derivatives. AgF and a mixture of CuF2 with copper powder also exhibited high activity in the reaction.
