摘要

研究了一种以可回收壳聚糖为生物聚合物基催化剂，在集中太阳辐射（CSR）下可持续进行Knoevenagel缩合反应的方法。这种绿色方法利用CSR作为可再生能源，消除了传统的加热和苛刻的试剂。该催化剂易于回收和重复使用，并具有最小的活性损失，确保了环境和经济优势。该方法在短的反应时间（8-28分钟）内提供了高收率（高达98%），展示了优异的原子经济性和能源效率（89-99%），符合绿色化学原则。图形抽象

Sustainable Knoevenagel condensation catalyzed by recyclable biopolymer under concentrated solar radiation

A sustainable Knoevenagel condensation protocol using recyclable chitosan as a biopolymer-based catalyst under concentrated solar radiation (CSR) has been developed. This green method eliminates conventional heating and harsh reagents by utilizing CSR as a renewable energy source. The catalyst is easily recoverable and reusable across multiple cycles with minimal activity loss, ensuring both environmental and economic advantages. The approach offers high yields (up to 98%) within short reaction times (8–28 min), demonstrating excellent atom economy and energy efficiency (89–99%) in alignment with green chemistry principles.
