Fe–PNP pincer complexes are the upcoming homogenous catalyst for organic reactions to overcome the need of much expensive Pd based catalysts. However, the lack of recovery and reusability are two significant challenges for homogeneous catalysts. We report herein a Fe–PNP complex immobilized on graphene oxide as a heterogeneous catalyst for the Suzuki coupling reactions. The prepared composite showed remarkable conversion efficiency towards Suzuki coupling reaction between phenylboronic acid and aryl halides. The study also discusses the parameters that are affecting the coupling reaction. The proposed catalyst can be quickly recovered and reused without any significant reduction in performance.
