Abstract

In this study, p-Phenylenediamine supported on nanocellulose (PDA@CNC) was designed. The prepared nanocatalyst was characterized with various analytical techniques such as FT-IR, XRD, TGA, SEM, and CHN. Nanocatalyst used for the synthesis of spiropyran oxide derivatives by designing a simple and efficient method using a three-part reaction between the Isatin derivatives, Malononitrile or Ethyl cyanoacetate and 1,3-dicarbonyl compound. Simple procedure, high yields, short reaction time and environmentally benign method are advantages of this protocol. The nanocatalyst was readily separated by filter and reusable without significant loss of its catalytic efficiency.

纳米纤维素负载对苯二胺 (PDA@CNC) 作为新型可回收纳米催化剂用于合成螺吡喃氧化物衍生物的制备与表征

摘要

在这项研究中,设计了纳米纤维素负载的对苯二胺(PDA@CNC)。所制备的纳米催化剂采用多种分析技术进行表征,如 FT-IR、XRD、TGA、SEM 和 CHN。通过使用靛红衍生物、丙二腈或氰基乙酸乙酯和 1,3-二羰基化合物之间的三部分反应设计一种简单有效的方法,用于合成螺吡喃氧化物衍生物的纳米催化剂。程序简单、收率高、反应时间短和环境友好是该协议的优点。纳米催化剂很容易通过过滤器分离并且可以重复使用而不会显着降低其催化效率。
