The synthesis of a diverse set of heteroleptic tris complexes of [Ru(L-H)2(L-L')]n+ (n = 0, 1, and 2) has been achieved via Ag+-assisted substitution of the chlorides from cis-[Ru(L-H)2Cl2] by chelating bidentate ligands (L-L') in ethanol medium. The cis-[Ru(L-R)2Cl2] complexes demonstrate remarkable catalytic efficiency in the selective hydrogenation of CO2 to formic acid under exceptionally mild conditions (at ambient pressure for both H2 and CO2). This low-pressure operation is particularly significant, as it eliminates the need for high-pressure reactors, aligning with the principles of green chemistry and energy efficiency. The catalysts afford good yields while maintaining excellent selectivity toward formic acid, with no detectable formation of more reduced by-products. Mechanistic investigations reveal that the in situ formation of a diimine-coordinated cis-Ru(H)2 species plays a pivotal role in CO2 activation and hydride transfer. These findings underscore the potential of Ru(II)-diazabutadiene complexes as efficient precatalysts for CO2 utilization, offering a sustainable and practical route for conversion of CO2 into formic acid.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 23","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compound 1 is an effective homogeneous catalyst for olefin epoxidation. The type of oxidant, namely tert-butyl hydroperoxide (TBHP) or H2O2, influences the catalytic performance. For cis-cyclooctene epoxidation, 1/TBHP led to 100% conversion after 4 h at 70 °C, and 1/H2O2 led to 80% conversion after 24 h at 70 °C. Catalyst recycling is feasible using an ionic liquid solvent with high affinity for the catalyst, and product separation via an extraction process. The catalytic potential of 1 was further explored for the chemical valorization of biomass-derived fatty acid methyl esters (FAMEs), namely C18-unsaturated methyl oleate and methyl linoleate derived from vegetable oils.

This Pd complex–SiO2 nanoparticle (NP) conjugate is synthesized through covalent binding of the pentadentate bis(N4-(2-ethylphenyl)) 2,6-diacetyl-pyridine TSC onto monodispersed SiO2, followed by coordination of Pd(II). Characteristic shifts of resonances in the Fourier-transform infrared spectra allowed confirming the SiO2 functionalization and the Pd-binding.

The absence of chloride in the XPS of the H2L–APTES–SiO2 conjugate strongly supports the successful covalent binding of the TSC onto the SiO2 NPs and is in line with the Sthiolate^Nimine^Npyridine^Namide coordination of Pd(II) in the conjugate that is also found in the model complex [Pd(L)].

Specially designed diboranes are synthesized for this purpose, being Lewis-acidic at boron and at the same time providing a filled BB bond orbital of high energy, from which electrons could be transferred to the substrate. A fine tuning of the substituents at the boron is required to balance the ambiphilic (electrophilic and nucleophilic) properties of the diborane. Moreover, diborane stability is an important issue for larger-scale applications, since strongly electrophilic diboranes are generally air sensitive. The discussion in the last sections focuses on diboranes with guanidinate substituents. These diboranes are air-stable and easy-to-handle sources of ambiphilic cationic diboranes and are efficiently synthesized by BB dehydrocoupling reactions. They are particularly suitable for processes in which substrate coordination and electron transfer proceed in two separate steps. The development of a transition-metal-like reactivity with stable, easy-to-handle diboranes paves the way to widen the applications of diboranes for further applications in synthetic chemistry.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 23","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202500214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
