摘要
本研究揭示了一种新型异相牛胶支撑 DABCO 功能化镍(II)催化剂的合成及其在 2-氨基-3-氰基-7-羟基-4H-苯合成中的应用。合成的 GG@Ni(II) 催化剂通过 FT-IR、XRD、EDX 和 SEM 技术进行了表征。在超声波条件下,在一锅多组分合成铬烯衍生物的过程中考察了这种合成异相催化剂的催化活性。在室温下,通过醛、丙二腈和间苯二酚的单锅多组分反应,设计了一条简单、良性和高效的超声介导路线来生产铬烯衍生物。所研究的超声介导合成路线具有反应时间短、反应条件绿色环保、操作简单、产率高、易于操作和纯化等显著优点。此外,有趣的是,从反应介质中定量回收催化剂并循环使用多达五次后,反应活性也没有明显下降。
Embedded Nickel Complex on Naturally Biodegradable Gaur Gum: Catalytic Application for the Green Synthesis of 2-Amino-3-Cyano-7-Hydroxy-4H-Chromenes
This study reveals that the synthesis of a novel heterogeneous gaur gum-supported DABCO functionalized nickel(II)catalyst and its application for the synthesis of 2-amino-3-cyano-7-hydroxy-4H-chromenes. The synthesized GG@Ni(II) catalyst was characterized by FT-IR, XRD, EDX, and SEM techniques. The catalytic activities of this synthesized heterogeneous catalyst were examined in one-pot multicomponent synthesis of chromene derivatives under ultrasonic condition. A simple, benign and highly efficient ultrasound-mediated route was designed to produce chromene derivatives via one-pot, multicomponent reaction of aldehyde, malononitrile, and resorcinol at room temperature. The ultrasound-mediated synthetic route was studied here exhibits some remarkable advantages such as short reaction times, green reaction conditions, operational simplicity, high yields, and easy work-up and purification steps. In addition to this interestingly found that there was unnoticeable loss of reactivity when the catalyst was quantitatively recovered from the reaction medium and recycled up to five times.
