Statment of the Problem:
The green solvent nature of the ionic liquids have potential application in many fields espacialy
battery, sensor, electro-organic synthesis due to non-volatile and having wide electrochemical potential window. However, the
generation of an electro-active species by paired-electrolysis is a difficult task. Inorder to harvest the high value of the ionic
liquid, herein, water content effect was investigated to reduce the V(III)(acetylacetone)
3
and its application as reductant. Initial
water content analysis with a 1-butyl-3 methyl imidazolium trifluoromethane sulfonate [BMIM CF

] ionic liquid revealed
a minimum cell potential of 6 V at 18 M water.
Methodology:
A Nafion 324 membrane divided plate and frame electrolytic cell was adopted for the paired electrolysis
experiments and the resutls obtined by a constant applied current method.
Findings:
Along with V(III)(acetylacetanone)3, other two compounds Ce(III)(SO

mediator quantification. The electrolytic reduction of V(III)(acetylacetonate) metal complex in 18 M water-containing BMIM

under optimized conditions revealed 65% of V(II)(acetylacetonate) formation. The applicability was checked by using
an organic compound dichloromethane, where found a well-defined change in the concentration of V(III)(acetylacetonate)
from 18% to 6% upon the addition of 20 mM dichloromethane demonstrated the that dichloromethane reduction follows the
mediated electrochemical reaction (MER).
Conclusions & Signifigans:
The developed system allows the use of galvanostatic mode to generate a electron active species
in an ionic liquid medium.
