A method for the photoredox fluoroalkylation of the C–H bond of azomethine compounds obtained from condensation of aldehydes and N-methylpyrrolidinone-derived amidrazones is described. The reactions are promoted with a carbazole-based organic photocatalyst under blue light irradiation. The ability of the cyclic nitrogen to stabilize a nitrogen-centered radical is believed to be a key factor responsible for the reaction efficiency.

Four new well-defined CuI complexes bearing a C2F5 ligand have been prepared and fully characterized: [(Ph3P)2CuC2F5] (2), [(bpy)CuC2F5] (3), [(Ph3P)Cu(phen)C2F5] (4), and [(IPr)CuC2F5] (5). X-ray structures of all four have been determined, showing that the C2F5-ligated Cu atom can be di- (5), tri- (2 and 3), and tetracoordinate (4). The mixed phen-PPh3 complex 4 is a highly efficient fluoroalkylating agent for a broad variety of acid chlorides. This high-yielding transformation represents the first general method for the synthesis of RCOC2F5 from the corresponding RCOCl. Four well-defined CuC2F5 complexes have been prepared and fully characterized, with [(phen)Cu(PPh3)C2F5] (phen=1,10-phenanthroline) proving to be a remarkably efficient fluoroalkylating agent for a broad variety of acid chlorides (see scheme). The procedure represents the first general method for the one-step conversion of RCOCl into valuable pentafluoroethyl ketones.
FLUORIDE ION CATALYZED ISOMERIZATION OF 2-ARYL-F-BUTENES
Burton, Donald J.,Headley, James A.
, p. 323 - 356 (2007/10/02)
A kinetic study of the fluoride ion catalyzed isomerization of a series of 2-aryl-F-1-butenes shows the reactions to be pseudo first order in olefin at constant fluoride ion concentration.The resultant Hammett plot is non-linear with a concave downward br
