Abstract
Bismuth(III) phenoxides have been synthesized by electrochemical reactions of 1‐naphthol, 2‐naphthol, 4‐aminophenol, 2‐nitrophenol, 4‐nitrophenol, 2‐hydroxybenzoic acid, p‐cresol, phenol, resorcinol, 2‐tert‐butylphenol and 2‐tert‐butyl‐4‐methoxyphenol at sacrificial bismuth anode and inert platinum cathode using tetrabutylammonium chloride as supporting electrolyte. The coordination compounds of these phenols with 1, 10‐phenanthroline and 2, 2ʼ‐bipyridyl have also been synthesized electrochemically. The solid products separated in the anode compartment have been isolated and characterized by elemental analysis and infrared spectral studies. Current efficiencies of these reactions are quite high.
Highlights
Electrochemical technique has widely been used in synthetic organic[1,2,3,4,5] and inorganic chemistry[6,7,8,9,10]
In continuation to our interest in the electrochemical synthesis of inorganic compounds[11,12,13], we report in this communication the synthesis of bismuth phenoxides and their coordination compounds

Summary
Electrochemical technique has widely been used in synthetic organic[1,2,3,4,5] and inorganic chemistry[6,7,8,9,10]. Infrared spectra of all the electrochemical products (except that of 2-hydroxybenzoic acid) show no absorption band in the region of 3600-3400 cm-1 thereby showing that the proton of phenolic group[15] in these reactions has been replaced by anodic bismuth.
