# Retraction: Magnetic nanoparticles modified with a copper(i) complex as a novel and efficient reusable catalyst for A3 coupling leading to C–N bond formation

## TL;DR

This paper is a retraction of a study that claimed a new reusable catalyst for chemical bond formation using copper-modified magnetic nanoparticles.

## Contribution

The paper does not contribute new findings, as it retracts a previously published study.

## Key findings

- The original study's claims about the catalyst's efficiency and reusability are being retracted.
- No new experimental or theoretical results are presented in this retraction.
