RETRACTED ARTICLE: An attractive and Efficient Procedure for Synthesis of Diaryl Ketones: Fe₃O₄@DH/Ph-ImH-Phen-Pd(0) Nanomaterial Catalyzed One-pot Carbonylative Suzuki Coupling Reactions

Diaryl ketones and his derivatives are biologically and medicinally very valuable compounds and have attracted the attention of many chemists. In this research project, we first synthesized the Fe₃O₄@DH/Ph-ImH-Phen-Pd(0) nanomaterial through a simple method and from the available materials, then we evaluated the application of its catalyst in the synthesis of diaryl ketones derivatives through the carbonylative Suzuki coupling reactions of arylboronic acids with aryl iodides and Cr(CO)₆. The structure of the synthesized nanocatalyst was well confirmed by several identification methods such as FT-IR, SEM, TEM, EDX, TGA, VSM, XRD and ICP-OES; it should be noted that the stability of the recovered Fe₃O₄@DH/Ph-ImH-Phen-Pd(0) nanomaterial catalyst was also confirmed by VSM and ICP-OES techniques. The results confirmed well that Fe₃O₄@DH/Ph-ImH-Phen-Pd(0) nanomaterial nanocomposite is a highly efficient nanomagnetic catalyst because all diaryl ketone products were synthesized with high yields under mild conditions. Based on the recycling experiments, the Fe₃O₄@AMBA-BiPy-Pd(0) catalyst was simply separated from the reaction mixture with an external magnet and could be reused for 8 times without significantly reducing its efficiency.
