中文摘要:
      CO2是一种来源丰富、价廉易得的C1资源。将CO2高值化利用是“双碳”目标实现的途径之一。苯并噻唑类化合物广泛应用于医药、农药等领域。因此,从绿色和可持续发展角度来看,利用CO2作为碳源合成杂环化合物苯并噻唑具有重要的意义。本文综述了氢气、硅烷和硼烷三类还原剂还原CO2和邻氨基苯硫酚反应合成苯并噻唑的方法,分析了各种方法的优缺点,阐述了采用不同还原剂的反应机理,并指出了这一领域面临的问题。另外,对该领域未来的发展方向进行了展望,如绿色环保溶剂的使用、新型高效还原剂的研究、苯并噻唑新合成路线的设计等。
英文摘要:
      CO2 is a low-cost and abundant C1 resource. Moreover, high-value utilization of CO2 is one of the pathways to achieve carbon peaking and carbon neutrality goals. Benzothiazoles are widely used in in many fields such as medicine, pesticide and so on. Therefore, from the perspective of green and sustainable development, the synthesis of heterocyclic compound benzothiazole using CO2 as the carbon resource is of great significance. Herein, the methods of synthesizing benzothiazole from the reaction of CO2 and o-aminothiophenol under the reductants such as hydrogen, silane or borane are reviewed. Furthermore, the advantages and disadvantages of various synthetic methods are analyzed, the CO2 reducing mechanism of different reductants is explained, and the problems faced in this field are pointed out. Additionally, the future development direction of this field is proposed, such as the use of green and environmentally friendly solvents, the research of new efficient reductants, and the design of new synthetic routes for benzothiazole.
