Untersuchungen zur Hydrazon‐Azo‐ und ‐En‐hydrazin‐Tautomerie sowie entsprechender Tautomerien bei Semicarbazonen durch Wasserstoffaustausch

Abstract: Hydrazone und Sernicarbazone einer Rdhe von Aldehyden und Ketonen tauschen in neutralem bithanol keinen an Kohlenstoff gebundenen Wasserstoff aus, d. h. da13 Azo-(1) und En-hydrazin-Tautomere (3) auch nicht in sehr geringer Konzentration vorhanden sind. In athanol. Kaliumhydroxid-Losung tauschen Aldehydderivate mit mono-substituiertem Stickstoff den am Carbonylkohlenstoffatom gebundenen Wasserstoff und, wenn vorhanden, auch a-standige Wasserstoffe aus. Bei Benzaldehyd-phenylhydrazon und p-substituierten Deriva… Show more
