摘要

Heck coupling reaction is widely employed in organic synthesis for the preparation of natural products, agrochemicals, and pharmaceutical and biologically active compounds. Heck coupling assists the reaction between aryl halides and alkene in the presence of palladium catalyst and phosphine ligands. The high cost of palladium makes it necessary to recycle the palladium catalyst. In the quest for developing an eco-friendly synthetic approach, a biopolymer and phytochemical-supported palladium heterogeneous catalyst has been explored due to its non-toxicity, abundance, and cost-effectiveness. Biopolymer decorated nanocatalysts play a significant role in the Heck coupling reactions by improving stability, recyclability, product yield, and selectivity. This review highlights recent progress in animal and plant-derived polysaccharides and phytochemical-decorated Pd nanocomposites for Heck coupling, focusing on substrate scope, catalytic performance, and recyclability. Besides, this article provides key insight for advancing sustainable organic transformations towards the development of therapeutic agents using green nanocatalysts.
