Abstract

The [Ni(S2PR2)2] complexes (R=i-PrO, PhO, or Et) can be conveniently prepared by reaction of [Ni{P(OPh)3}4] with [R2P(S)S]2 (R=i-PrO, PhO, or Et) in refluxing CHCl3. The electrochemical behaviour of the complexes in CH2Cl2 and MeCN has been studied by cyclic voltammetry and coulometry. The oxidation of complexes at a glassy carbon reveals an e.c. mechanism. The [Ni(S2PR2)2] complexes undergo a one-electron irreversible reduction.
