C. Cannes et al., Electroassisted catalysis of the reductive coupling of 2-bromooctane and methyl vinyl ketone by a binuclear cobalt-salen-iron complex in DMF solution: electrosynthesis and cyclic voltammetry analysis, NEW J CHEM, 23(5), 1999, pp. 489-494
We report in this study the combined use of a CoSalen [H(2)Salen = bis(sali
cylidene)ethane-1,2-diamine] complex and an undivided electrochemical cell
process in the electroassisted reductive coupling of 2-bromooctane and meth
yl vinyl ketone with satisfactory results. Correlation between the electroa
nalytical analysis of the reactivity of CoSalen in the presence of 2-bromoo
ctane and methyl vinyl ketone and the electrosynthesis performed in an undi
vided electrochemical cell with a sacrificial iron anode allows us to sugge
st that a heterobinuclear Co-Salen-Fe complex is the effective catalyst of
the considered reaction. Stability of this intermediate during preparative
electrolysis is also discussed.
