Description |
Electrochemical reduction of four activated
olefins namely cyclohexenone (CH), cyclopentenone (CP),
methylmethacrylate (MMA), acrylonitrile (AN) in the
absence and presence of benzylbromide (BBr) were investigated
in CTAB/n-hexane/n-butanol/water based bicontinuous
microemulsion (lE). Both cyclic voltammetric studies and
galvanostatic preparative electrolysis were carried out. Cyclic
voltammetric results in lE were also comparedwith those in
N,N-dimehtylformamide (DMF) medium. Adsorption effects
are observed both inDMF and lE.ANundergoes one electron
reduction in aprotic solvent and two electron reduction in lE.
CH, CP, BBr undergo one electron reduction and yield
significant homolytic coupled products under galvanostatic
conditions. AN and MMA lead to two electron reduction
under identical conditions. In the presence ofBBr, CHand CP
alone yield significant heterolytic coupled products with
simultaneous competitive resin formation. Reduction of AN
leads to the formation of a identifiable quantity of propylamine
and 3-phenylpropylamine in the absence and in the presence
of BBr, respectively.
