40. Diazoaldehyde chemistry: Part 3. Synthesis of 4-acyl-1H-1,2,3-triazole derivatives

Ten new α -diazo-β-oxoaldehydes were condensed with aniline, ammonia, hydroxylamine, and semicarbazide to yield new 4-acyl-(1-substituted)-1H-1,2,3-triazoles in moderate-to-good yields. The method is simple and regiospecific. The latter feature makes this method superior to the widely used acylacetylene + azide approach.

TRANSFER OF THE DIAZO FUNCTION IN THE SERIES OF FLUORINATED 1,3-DIKETONES

In the reaction of fluorinated 1,3-diketones with p-toluenesulfonyl azide under the conditions of diazo transfer hydrolytic elimination of the perfluoroacyl group occurs, and acyldiazomethanes are formed instead of the fluorine-containing diazo diketones.The reaction can be used for the synthesis of difficultly obtainable and labile 2-diazo ketones.
