Abstract

Nano-Fe₃O₄–l-cysteine as a superior catalyst has been used for the synthesis of indeno [1,2-c]pyrazol-4(1H)-ones through a three-component reaction of phenylhydrazine, aromatic aldehydes and indan-1,2,3-trione at room temperature in acetonitrile. The catalyst has been characterized by XRD, FT-IR, SEM, EDS, TGA and VSM. This method provides several advantages including mild reaction conditions, excellent yields in short times, the reusability of the catalyst and low catalyst loading.

纳米 Fe3O4-半胱氨酸作为合成茚并[1,2-c]吡唑-4(1H)-酮的优良催化剂

摘要

Nano-Fe ₃ O ₄ - l-半胱氨酸作为一种优异的催化剂已被用于通过苯肼、芳香醛和茚满的三组分反应合成茚并[1,2-c]吡唑-4(1H)-ones -1,2,3-三酮在室温下的乙腈中。通过XRD、FT-IR、SEM、EDS、TGA和VSM对催化剂进行了表征。该方法具有多个优点，包括反应条件温和、短时间内收率高、催化剂的可重复使用性和催化剂负载量低。
