Electrochemical Synthesis of the Ni(O)-Diazabutadiene Complexes
Coulombeix, Jose,Emmenegger, Franz-Peter
, p. 248 - 254 (1985)
The electrochemical reduction of Ni salts in the presence of diazabutadiene ligands (DAB= R-N=CH-CH=N-R, R=t-Bu, o-xylyl, p-anisoyl, p-tolyl) has been studied in DMF by cyclic voltammetry and rotating disc polarography.In solutions containing DAB and halide X-, Ni(II) can be reduced to Ni(DAB)2, and the features of this reduction agree with a mechanism where the second DAB replaces X- in the coordination sphere of Ni only after its reduction to Ni(O).Rather concentrated (ca. 0.1 M) solutions of NiBr2*DME and DAB in DMF have been electrolyzed without a supporting electrolyte, making the isolation of the product Ni(DAB)2 particularly easy.Thus, gram quantities of Ni(DAB)2 can be conveniently prepared within a few hours.

With N-aromatic substituted diazadienes (DAD) (R1, R2 = H, CH3 and R3 = R4 = aryl) nickel(0) forms complexes of composition (DAD)2Ni which are prepared preferably by reduction of Ni(II) salts in the pr
