- Abstract
An efficient protocol was developed for the nano CoCuFe2O4‐catalyzed C‐N and C‐S bond formation. By this catalytic system, both amine and sulfide‐based structural motifs were formed efficiently in aryl halide‐free route. The amination reaction of phenyl boronic acid with various types of amines was conducted under ligand‐free conditions, in ethanol as a green solvent at 60°C. Unsymmetrical diaryl/aryl alkyl sulfide synthesis via the coupling reaction of arylboronic acids with thiols was also conducted. The nano cobalt‐copper ferrite was used as a heterogenous efficient, inexpensive, magnetically separable and recyclable catalyst that can be used for several cycles. Cost‐effective and atom‐economic approach to C‐heteroatom bond formation. Green and practical method for preparation of N‐arylamines via magnetically separable and recyclable catalyst. Employing user‐friendly arylating agent (aryl boronic acid).
