Photochemstry. IV. Photolyses of 3-Chloro- and 3-Hydroxy-6-phenylpyridazines in Methanol Containing Hydrogen Chloride

Photolysis of 3-hydroxy-6-phenylpyridazine (III) in CH3OH containing 5% HCl, afforded methyl 3-benzoylpropanoate (V) and methyl 2-methyl-3-benzoylpropanoate (VI), and three kinds of nitrogen free compounds. Similarly, 3-chloro-6-phenylpyridazine (IV) afforded V, methylated pyridazines (VII, VIII, IX...

Zusammenfassung:Photolysis of 3-hydroxy-6-phenylpyridazine (III) in CH3OH containing 5% HCl, afforded methyl 3-benzoylpropanoate (V) and methyl 2-methyl-3-benzoylpropanoate (VI), and three kinds of nitrogen free compounds. Similarly, 3-chloro-6-phenylpyridazine (IV) afforded V, methylated pyridazines (VII, VIII, IX, X, and XI), hydroxymethylated pyridazine (XI), and small amounts of nitrogen free compounds.
