    Model studies show that displacement of fluorine, rather than chlorine, occurs upon reaction of 3,5-dichloro-2,4,6-trifluoropyridine with sodium methoxide and phenoxide. Subsequent hydro-dechlorination can be achieved by reaction with lithium aluminium hydride whereas reaction of sodium in iso-propanol leads to formation of the tri-iso-propoxy pyridine derivative, via nucleophilic substitution of the

    An alternative approach to formation of a C-C bond at a meta-position of an aromatic compound is disclosed that employs an ethylenically unsaturated bicyclic compound as a transient mediator to achieve meta-selective C-H activation with a simple and common ortho-directing group. The use of a pyridine-based ligand assists in relaying the palladium catalyst to the meta-position by the unsaturated bicyclic compound following initial ortho-C-H activation.
