They have been broadly employed in the preparation of multiple carbon molecules. The Sonogashira reaction is a well-known, efficient, and useful reaction widely employed in organic chemistry. They are used in multiple fields like organic synthesis, synthesis of heterocycles, pharmaceuticals, natural products, and nanomaterials. This coupling reaction is a renowned procedure for sp2-carbon-sp-carbon bond construction in organic synthesis. This review intends to summarize the usage of β-cyclodextrin-based catalyst systems in carbon-carbon coupling Sonogashira reactions and overview articles up to 2025.

A detailed examination of Zn-MOFs photocatalytic degradation mechanisms highlights critical steps, including light absorption, electron-hole pair formation, charge separation, and reactive radical generation, which collectively drive efficient pollutant breakdown. The unique structural and chemical properties of Zn-MOFs, such as their high surface area, tunable bandgap, and coordinated action of organic linkers and metal nodes, are explored in the context of their photocatalytic efficiency. Key synthetic methods–hydrothermal, solvothermal, and microwave-assisted techniques–are discussed alongside characterization approaches like X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analysis, and UV–Vis spectroscopy, which elucidate the structural, surface, and optical properties of Zn-MOFs. Factors influencing photocatalytic performance, such as dye concentration, pH, photocatalyst dosage, and temperature, are analyzed to optimize their application. A comparative analysis with other MOFs underscores the strengths and limitations of Zn-MOFs, while the conclusion addresses current challenges and future directions, emphasizing their potential in sustainable water purification and environmental remediation.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1030 ","pages":"Article 123572"},"PeriodicalIF":2.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
