T. Braun et al., Catalytic C-F activation of polyfluorinated pyridines by nickel-mediated cross-coupling reactions, CHEM COMMUN, (21), 2001, pp. 2254-2255
The cross-coupling reaction of pentafluoropyridine with tributyl( vinyl) ti
n affording 2-vinyltetrafluoropyridine by activation of a carbon-fluorine b
ond is catalysed by [NiF( 2-C5NF4)( PEt3)(2)]; a similar reaction is observ
ed with 2,3,5,6- tetrafluoropyridine.
