| Abstract: | by MnO2-oxidation of 3-pyridazinemethanol is reported. Properties of2 and its reactions with NH-compounds and methyl-pyridazines (3, 5) are studied. Reaction of2 with3 yields mainly products of aldol addition (10, 12). In contrast to pyridazinyl-4-carbinols elimination of H2O from10 leads to the alkene11. Isolation of the di-pyridazinyl-ethane6 as main product of reaction of2 with5 however shows, that thermally induced dismutation cannot be excluded also on pyridazinyl-3-carbinols.
