Electrochemistry of cycloaddition products of olefins with nickel dithiolenes: A reinvestigation of the reduction of the 1 : 1 adduct between Ni(S2C2(CF3)(2))(2) and norbornadiene
The reduction of Ni(S2C2(CF3)(2))(2)(C7H8) (3) proceeds by an overall two-electron irreversible process through an ECE mechanism. The reduction potential of 3 is about 700 mV negative of that in an earlier report which is shown to result from contamination of the sample by the monoanion of the olefin-free complex [Ni(S2C2(CF3)(2))(2)](-).
