Nanosized-Ni Doped on Montmorillonite Catalysed Suzuki–Miyaura Coupling Reactions
This work reports the synthesis and characterization of Nanosized-Ni doped montmorillonite heterocatalyst and its application for Suzuki Miyaura cross coupling of aryl iodides with aryl boronic acids. The catalyst is highly selective and did not give any other byproducts. The reaction was complete within 24 h with > 98% yield. Nickel was uniformly dispersed on the catalyst with approximately 4.0 ± 2 nm clusters of Ni. The solvent, base, catalyst loading, and catalyst precursors were varied to obtain optimum reaction conditions for highest yield. The catalyst was recovered and reused for reactions demonstrating excellent recyclability with high yield. Ni doped montmorillonite catalyst is very effective for Suzuki Miyaura cross coupling reactions and can be used to replace expensive Pd-based catalysts with earth abundant and inexpensive Ni-based catalysts.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
