The electrochemical reduction of some substituted π-cyclopentadienylnickel(II) complexes

Abstract The electrochemical reduction of the complexes [CpNi(PR 3 ) 2 ] + , where R = C 2 H 5 , C 3 H 7 , C 4 H 9 or [C 6 Ni,(diphos)] + and [CpNi(diars) + in acetonitrile is described and the data are compared with those for the complexes Cp 2 Ni, [Ni(PR 3 ) 4 ] 2 + and Ni(diphos) 2+ 2 .
