Electrochemical Behaviour of Some Thiazolobenzimidazol-3(2H)-one Derivatives. Part 1. Electroreduction of a Series of 2-Arylazothiazolobenzimidazol-3(2H)-ones

The electrochemical reduction of a series of 2-arylazothiazolobenzimidazol-3(2H)-ones has been investigated.A mechanism for the electrode process covering a wide range of pH values is proposed, discussed, and clarified via model compounds, polarographic analysis, pKa determination, and interpretation of Hammett's ?/E1/2 relations.Large-scale preparative electrolysis of the title and model compounds was carried out and the products were isolated and identified.
