摘要

我们提出了一种碳酸铯介导的方法，通过选择性热解聚将聚碳酸丙烯（PPC）废物升级为β-羟基硫化物、硒化物和苯氧化物。该工艺可耐受多种亲核试剂，包括来自多层塑料的亲核试剂。机理研究支持芳基硫酸铯驱动的亲核降解。β-羟基产物易于功能化，碱是可回收的，为PPC增值提供了可持续的途径。

Sustainable base-mediated chemical upcycling of poly (propylene carbonate) to β-hydroxy sulfides and oxides

We present a cesium carbonate–mediated method to upcycle poly(propylene carbonate) (PPC) waste into β-hydroxy sulfides, selenides, and phenoxides via selective thermal depolymerization. The process tolerates diverse nucleophiles, including those from multilayer plastics. Mechanistic studies support a cesium aryl thiolate–driven nucleophilic degradation. The β-hydroxy products are easily functionalized, and the base is recyclable, offering a sustainable route for PPC valorization.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
