Abstract

Cyclic voltammetry at hanging mercury drop electrode (HMDE) and differential pulse polarography at dropping mercury electrode (DME) are used in two-electron cleavage of carbon-halogen bond in α - methylbenzylchloride in the presence of tetramethylammonium hexafluorophosphate (TMAHP), tetramethylammonium bromide (TEAB), tetra-n-propylammonium

perchlorate (TPAP), and tetrabutylammonium iodide (TBAI) as the supporting electrolytes. The reduction potentials of α - methylbenzylchloride are found to be in the range – 2.14 to -2.56V vs Ag/AgCl<i> </i>and arc shown to be sensitive

to the nature of the cation of the supporting electrolyte. As the size of the tetraalkylammonium cation of the supporting electrolyte increases the voltammetric/polarographic peak moves towards more negative potentials. The analytical procedure is developed by differential pulse polarography for the determination of α - methylbenzylchloride during the electrosynthesis
