Abstract

Electrochemical reactions of methanol, ethanol, propan-l-ol, butan-1-ol, pentan-1-ol, hexan-1-ol, heptan-1-ol, octan-1-ol, nonan-1-ol and decan-1-ol (ROH) at sacrificial aluminium anode and inert platinum cathode in the presence of tetrabutylammonium chloride as a conductive additive and acetonitrile as solvent yield aluminium(III) alkoxides. On refluxing with ligand (L) {where L = 2,2’-bipyridyl and 1,10-phenanthroline} these alkoxides don’t form coordination compounds. However, the coordination compounds have been prepared by electrolyzing the solution of above alcohols in the presence of ligand (L) at aluminium anode. These products have been characterized by microanalysis, physical measurements and IR spectral studies.General formula conform to M(OR)3 and M(OR)3.L.{where M- Aluminium and L- ligand}.All these reactions proceed with high current efficiencies.

Highlights

  • Electrochemical synthetic technique is one of the challenging techniques to this technological world

  • Tetrabutylammonium chloride was crystallized from conductivity water and dried under reduced pressure at 100°C

  • Where Al(+) is Aluminium anode, Pt(-) is platinum cathode, Bu4NCl is tetrabutylammonium chloride and ROH is alcohol used in the system

Summary

Introduction

Electrochemical synthetic technique is one of the challenging techniques to this technological world. Where Al(+) is Aluminium anode, Pt(-) is platinum cathode, Bu4NCl is tetrabutylammonium chloride (supporting electrolyte) and ROH is alcohol used in the system. Presence of these bands and absence of bands due to hydroxyl group in the electrochemical products indicate that the hydrogen of the alcohol has been replaced by anodic aluminium.
