The structure and composition of the complex were confirmed by the presence of a sharp vibrational band appearing at 402, 518, and 578 cm⁻¹, characteristic of the Co-O bond, along with ¹H NMR and mass spectrometry. The surface grafting of the cobalt complex was evident from FTIR, low-angle powder XRD, TGA, nitrogen adsorption-desorption, and FESEM analyses. The catalytic behavior of homogeneous and heterogenized cobalt complex was evaluated for the oxidation of benzhydrol and various primary and secondary alcohols using <em>t</em>‑butyl hydroperoxide (TBHP) as the oxidant. The heterogeneous system demonstrated excellent activity and reusability, achieving complete conversion of benzhydrol to benzophenone at 90 °C. Studies on different substances showed that the system worked very well for cinnamyl alcohol and had moderate activity with benzyl alcohol, furfuryl alcohol, and cyclohexanol, with the differences due to the unique structures of each substance. The proposed mechanism involves the formation of a cobalt-peroxo intermediate facilitating alcohol oxidation. The catalyst exhibited remarkable stability and retained its activity over multiple cycles, underscoring its potential as an efficient and reusable system for selective alcohol oxidation under mild conditions.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1038 ","pages":"Article 123748"},"PeriodicalIF":2.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330123","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}

As an intermediate, 5-HMF offers a sustainable pathway to replace petroleum-based products and is considered an ideal candidate for the bio-based chemical industry. Its importance lies not only in its wide range of applications in chemical synthesis but also in its potential to contribute to developing sustainable energy solutions. The conversion of biomass-derived sugars into 5-HMF represents a crucial step in advancing renewable energy technologies and reducing dependency on fossil fuels. In this study, sulfonic melamine-based ionic liquids (MILs) were successfully immobilized onto SBA-16 modified with (3-chloropropyl) trimethoxysilane, resulting in the synthesis of a highly efficient solid acid catalyst. This approach ensures high catalyst stability and activity in the dehydration of fructose to 5-HMF. Characterization methods showed that the mesostructure of SBA-16 remained intact following the immobilization of the IL. The catalyst was evaluated for its catalytic efficiency in producing 5-HMF, with various reaction parameters optimized to achieve a maximum yield. Under optimal conditions, a 98 % yield of 5-HMF was achieved after 30 min at 100 °C in DMSO with a catalyst loading of 15 mg. Moreover, the catalyst exhibited excellent recyclability, maintaining high catalytic activity across seven consecutive cycles.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1038 ","pages":"Article 123736"},"PeriodicalIF":2.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221904","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}
