triphenylphosphine and benzylic electrophiles have been examined in an ionic liquid to probe interactions with species along the reaction coordinate. Trends in the rate constant were found on both varying the leaving group and the electronic nature of the aromatic ring. In all the cases considered, interactions between the components of the ionic liquid and the transition state were shown to be more significant

New bisferrocenyl pyridine, nitrile and nitro terminated compounds have been obtained by Wittig reactions. The coordination capabilities of the nitrile and pyridine compounds have been proved by coordination to M(CO)5 fragments, M being Cr, Mo or W. The electrochemical properties of the compounds have been studied by means of cyclic voltammetry, showing an effective electronic coupling between the two ferrocenyl fragments. The crystal structures of several of the described complexes are reported, showing that, in all cases, the syn conformation on the 1,1′ bis-substituted ferrocene is preferred over the anti one.
