Under the influence of bases 1-ethyl-5-aryl-1,2,4-triazinium salts containing an alkylthio group at position 3 undergo unusual dimerization involving the carbon atoms of the N-ethyl group and the C6 atom of the heterocycle.The structure of the dimers was established by physical methods, including x-ray crystallographic analysis.During investigation of the reaction mechanism the products from addition of methanol at the C6 atom and the 1-ethyl-1,2,4-triazinyl radical, having a resolved ESR spectrum, were detected.The possible mechanism of dimerization is discussed.
