Synthesis of (E)-2-(Chloro (Phenyl) Methylene)-1-(6-Chloroquinoxalin-2-yl) Hydrazine Derivatives by Reusable Fe3O4 Nano Powder at Room Temperature

Abstract

A multicomponent reaction (MCR) for the synthesis of five novel N'-(6-chloroquinoxalin-2-yl) benzohydrazide derivatives in excellent yields at room temperature have been achieved via a reaction between 1-(6-chloroquinoxalin-2-yl) hydrazine was added 4-chloroethyl benzoyl chloride followed by the addition of Fe3O4 nanoparticles. This was applied as an efficient and recoverable nanocatalyst for the one‐pot synthesis of hydrazine Derivatives. The catalyst was magnetically recovered and reused for 4 consecutive cycles without significant loss of its activity and selectivity. Fe3O4 Nano catalyst was prepared by the co-precipitation method and characterized by X-ray diffraction (XRD), FT-IR, TEM, VSM, and analyses. This study presents an efficient multicomponent protocol, which provides several advantages, such as short reaction times, high yields, and easy working up this work.
