Chemistry of 2-Arylhydrazonals: Utility of Substituted 2-Arylhydrazono-3-Oxoalkanals as Precursors for 3-Oxoalkanonitriles,3-Aminoisoxazole and 1,2,3- and 1,2,4-Triazoles
Efficient routes to 2-arylhydrazono-3-oxoalkanonitriles, 1,2,3- and 1,2,4-triazoles, and 3-aminoisoxazole utilising the oximes of the title hydrazones are reported. The behaviour of the oximes on pyrolysis in the gas phase and by flash vacuum is analysed. X-ray crystallography were used to confirm the structure of the triazole 10b and the 3-oxoalkanonitrile 12f.
