Aggregates of perylene bisimide stabilized superparamagnetic Fe3O4 nanoparticles: an efficient catalyst for the preparation of propargylamines and quinolines via C–H activation

Abstract

Aggregates of the perylene bisimide derivative 3 act as reactors and stabilizers for the preparation of superparamagnetic Fe₃O₄ nanoparticles (NPs) which exhibit excellent catalytic efficiency in (i) A³-coupling and aldehyde free coupling reactions for the preparation of propargylamines and (ii) tandem intramolecular cyclization reaction for the synthesis of quinolines via C–H activation.
