Mitigating the associated ecological and toxicological impacts necessitates the development of environmentally benign strategies for their reduction to aminoaromatics. This study reports the synthesis of novel heterogeneous N,S co-doped reduced graphene oxide/ NiFe₂O₄ (N,S-rGO/NiFe₂O₄) nanocomposites via a one-step hydrothermal method. This approach simultaneously incorporates nitrogen and sulfur dopants into the graphene oxide matrix and integrates NiFe₂O₄ nanoparticles within the graphene layers. The structural, morphological, optical, and photocatalytic properties of the nanocomposites were systematically characterized using a comprehensive array of analytical techniques. The results confirm the successful co-doping of nitrogen and sulfur into the graphene oxide framework and the effective immobilization of NiFe₂O₄ nanoparticles onto the rGO surface. Notably, the synthesized nanocomposites exhibited outstanding photocatalytic activity under visible light, achieving complete reduction of nitrobenzene to aniline with 100 % conversion efficiency within 45 min, using hydrazine monohydrate as the hydrogen donor. Moreover, the photocatalyst demonstrated excellent stability and reusability, maintaining consistent catalytic performance over six consecutive cycles without any detectable loss in material integrity or conversion efficiency.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1035 ","pages":"Article 123680"},"PeriodicalIF":2.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899125","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}

Herein, a mechanistic study is described of the nickel-catalyzed cross-coupling of phenylmagnesium chloride with 4-fluoroanisole by the aid of density functional theory (DFT) calculations. The computations show that aryl C−F bond activation is assisted by the cooperative catalysis of nucleophilic nickel bridged by the deprotonated air-stable secondary phosphine oxide (SPO) ligand, along with Lewis acidic magnesium. Compared to the cleavage of C−O bond, this unusual chemoselective activation of C−F bond is controlled by heterolytic bond dissociation energy (HBDE). A linear free energy relationship (LFER) between fluoroarenes' HBDE and C−F activation energy barriers was established, further confirming that HBDE plays a significant role in the activation of aryl C−F bonds.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1035 ","pages":"Article 123674"},"PeriodicalIF":2.1,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887953","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}
