Abstract

Pyridazinyl-4-carbinols (e.g.4, 9a, 9b) are found to dismutate at elevated temperatures yielding 4-alkyl-pyridazines and pyridazinyl ketones. This explains formation of unusual products in certain condensation reactions of pyridazine-4-carboxaldehyde. The mechanism of dismutation is discussed, IR-,1H-NMR- and mass spectral data of the new pyridazine derivatives4, 5, 6, 8, 11a are presented.
