The Electrochemical Reduction of Compounds with the Group. III <i>as</i>-Triazines

Abstract

The electrochemical reduction of as-triazines 3-one or -thione leads to a 1,4-dihydro derivative which rearranges into a 4,5-dihydro compound which is further reducible to an imidazolone or a tetrahydro as-triazine 3-one. In the case of simple as-triazine the 1,4-dihydro compound rearranges either to a 1,2- or to a 4,5-dihydro compound. This last derivative can be reduced to an imidazole or a tetrahydro as-triazine. The mechanisms are discussed.
