Reactions under Pressure: Synthesis of Functionally Substituted Arylhydrazonal Derivatives as Precursors of Novel Pyridazines and Nicotinates

Al-Johani, M. A.,Alqahtani, N. F.,Elnagdi, N. Hilmy,Mousally, S. M.,Zaydi, K. M. Al

, p. 710 - 719 (2020/07/02)

Abstract: Q-tube assisted multicomponent synthesis of novel arylhydrazonals, pyridazines and nicotinates has been explored. The target molecules have been prepared via one pot reaction of arylhydrazonals with activated methylene nitriles in either ethanol
