One-pot multicomponent synthesis of thieno[2,3-<i>b</i>]indoles catalyzed by a magnetic nanoparticle-supported [Urea]<sub>4</sub>[ZnCl<sub>2</sub>] deep eutectic solvent

Abstract
C NMR, HRMS (ESI). Due to the deep eutectic solvent coated surface of the magnetic nanoparticles, the catalyst could be recovered by an external magnet and reused in five consecutive runs without a considerable decrease in catalytic activity.
