Definition of Hydrazones. Meaning of Hydrazones. Synonyms of Hydrazones

- react with aldehydes and ketones to give hydrazones. Phenylhydrazine reacts with reducing sugars to form hydrazones known as osazones, which was developed...
- systems. Hydrazones are usually very stable towards solvolysis, and conversion to the ketone can require vigorous conditions. Also, aldehydic hydrazones often...
- Acetone hydrazone (isopropylidenehydrazine) is the product of condensation of acetone and hydrazine, as typical for hydrazone formation. It is an intermediate...
- roots with the 1911 discovery by Wieland and Roseeu that the reaction of hydrazones with iodine alone (without base) results in the azine dimer (structure...
- procedure by refluxing carbonyl hydrazones and pot****ium tert-butoxide in dry toluene. Slow addition of the hydrazone is not necessary and it was found...
- Reutov, O. A. (May 1966). "Reactions of hydrazones and azines with metal salts Communication 5. Reactions of hydrazones and azines with mercuric halides"....
- exists in two tautomeric forms: hydrazide imides (RC(=NH)NHNH2) and amide hydrazones (RC(NH2)=NNH2). Some amidrazones have been emplo**** as insecticides. They...
- convert C-Cl to C-H. With ketones and aldehydes, it condenses to give the hydrazones: CH3C6H4SO2NHNH2 + R2C=O → CH3C6H4SO2NHN=CR2 + H2O Upon heating in solution...
- 2-diazopropane [fr] from acetone hydrazone. Other oxidizing reagents are lead tetraacetate, manganese dioxide and the Swern reagent. Tosyl hydrazones RRC=N-NHTs are reacted...
- hydrazide is used to generate toluenesulfonyl hydrazones. When derived from ketones, these hydrazones parti****te in the Shapiro reaction and the Eschenmoser–Tanabe...
