Benzoylacetonitrile and beta-aminocinnamonitrile are shown to possess potent antiinflammatory activity in the rat adjuvant arthritis model. In a series of phenyl-substituted analogues, only o-, m-, and p-fluorobenzoylacetonitrile and m- and p-fluoro-beta-aminocinnamonitrile retained activity. Additionally, beta-amino-2- and beta-amino-3-thiopheneacrylonitrile and beta-oxo-2- and beta-oxo-3-thiophenepropionitrile

A variety of nitro and nitrile compounds were fluorinated in good yields by Selectfluor under mild conditions. For these transformations to be successful, it is crucial to select proper amounts of an appropriate base as a function of the properties of the substrate and also to use Selectfluor only as required.

An improved substrate scope for the mechanochemical electrophilicfluorination of dicarbonyls is reported. The applicable substrates have now been broadened to include liquid β-ketoesters. Key to this capability is the inclusion of a grinding auxiliary (NaCl) to improve mass transfer and prevent pasting or gumming of the reaction mixture. Notably, the use of a small amount of acetonitrile is critical

A new synthesis of fluorinated pyrazoles, a class of compounds with potential in medicinal chemistry, is described. The treatment of benzoylfluoroacetonitrile with hydrazine yielded the expected new 3-amino-4-fluoropyrazole, while the analogous reaction of α-cyano-α,α-difluoroketones with hydrazine in refluxing isopropanol surprisingly gave rise to 3-unsubstituted 4-fluoropyrazoles via an unprecedented
