Developing a self-sensitized catalyst from earth-abundant elements capable of efficient light harvesting and electron transfer is crucial for enhancing the efficacy CO 2 reduction, environmental cleanup, improving clean energy prospects.
Developing a function-integrated catalyst from earth-abundant elements, capable of efficient light harvesting and electron transfer, is crucial for enhancing the efficacy CO2 transformation, critical step in environmental cleanup advancing clean energy prospects. Traditional approaches relying on external photosensitizers, comprising 4d/5d metal complexes, often face challenges intermolecular attachment photosensitizing arms to increases dependency intramolecular transfer kinetics,...
There is growing demand for the utilization of first-row transition metal complexes in light-driven processes instead their conventional noble counterparts due to greater sustainability complexes. However, major drawback ultrafast lifetime electronic excited states these complexes, particularly those d
High-valent metal-fluoride complexes are currently being explored for concerted proton-electron transfer (CPET) reactions, the driving force high bond dissociation energy of H-F (BDEH-F = 135 kcal/mol) that is formed after reaction. Ni(III)-fluoride-based on pyridine dicarboxamide pincer ligand framework have been utilized CPET reactions toward phenols and hydrocarbons. We replaced central with an N-heterocyclic carbene to probe its effect in both stabilizing high-valent Ni(III) state...
Ni(II)-tetradentate amido-quinoline complexes effectively catalysed C-H chlorination of a series hydrocarbons in the presence NaOCl and acetic acid. The bond dissociation energy C(sp3)-H substrates varies from 99.3 kcal mol-1 (cyclohexane) to 87 (ethyl benzene). Exclusively chlorinated products (TON: 220 for cyclohexane) were obtained without any hydroxylated products, thus mimicking activity halogenase enzyme.
Cu( ii )-tetradentate amido-quinoline complexes effectively catalysed aromatic C–H hydroxylation using H 2 O as an oxidant in the absence of external base with a high selectivity around 90% for phenols via non-radical pathway (TON ≥720).
The water-soluble Nickel(II)-guanidine-based complexes successfully catalyzed the C-H chlorination of a series hydrocarbons in presence NaOCl and acetic acid water-chloroform (7:3, biphasic condition) at room temperature....
