Fe3O4/PANI/CuI as sustainable heterogenous nanocatalyst for A3 coupling.

The prepared copper iodide nanoparticles were impregnated on the support of ferrite nanoparticles functionalized with polyaniline, resulting in a magnetically recoverable heterogeneous nanocomposite. The catalytic activity of the prepared nanocomposite was evaluated for the synthesis of propargylamine derivatives via A3 coupling under mild conditions. Techniques such as XRD, FTIR, EDAX, XPS, TEM, and FESEM were used to characterize the effective and unique heterogeneous Fe3O4/PANI/CuI nanocomposite developed in this work. This current study has several advantages, including a short reaction time, solvent-free conditions, high product yield, ideal chemistry matrices values, reusability for up to seven cycles, and magnetic retrievability.
