Sonochemically synthesis of pyrazolones using reusable catalyst CuI nanoparticles that was prepared by sonication
چکیده انگلیسی

A simple and green process to prepare copper iodide in nano scale via sonication was carried out. Subsequently, this nanoparticles was used as an efficient catalyst for the synthesis of 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones via four-component reaction of hydrazine, ethyl acetoacetate, aldehyde and β-naphthol in water under ultrasound irradiation. The combinatorial synthesis was attained for this procedure with applying ultrasound irradiation while making use of water as green ambient. Simple work-up, excellent yield of products and short reaction times are some of the important features of this protocol. Notably, this catalyst could be recycled and reused for five times without noticeably decreasing the catalytic activity.


► Ultrasonic assisted synthesis of copper iodide in nano scale.
► We used nano CuI as an efficient catalyst for the preparation of pyrazolones.
► By sonication method pyrazolones were synthesized in high yields and short times.
