The integration of ligand-to-metal charge transfer (LMCT) catalytic paradigms with radical intermediates has transformed the selective functionalization inert C-H bonds, facilitating use nonprecious metal catalysts in demanding transformations. Notably, aerobic carbonylation methane to acetic acid remains formidable due rapid oxidation methyl radicals, producing undesired C1 oxygenates. We present an iron terpyridine catalyst utilizing LMCT achieve exceptional C2/C1 selectivity through synergistic photoexcitation, generation, and carbonylation. Mechanistic studies highlight critical roles Fe(II) Fe-carbonyl complexes bypassing via a rebound-like pathway, unlocking unprecedented efficiency

The challenging synthesis of thermodynamic-unfavored cis-olefins through catalytic cross-coupling reactions requires the synergistic interaction substrate-activating units and configuration-regulating catalysts. Successfully hitting these two birds with one stone, we herein develop a convenient photoredox access to Z-alkenes from alkynes light alkanes bifunctional iron-catalyzed system possessing both C(sp

Nitroaromatics, as an important member and source of nitrogen-containing aromatics, is bringing enormous economic benefits in fields pharmaceuticals, dyes, pesticides, functional materials, fertilizers, explosives. Nonetheless, the notoriously polluting nitration industry, which suffers from excessive discharge fumes waste acids, poor group tolerance, tremendous purification difficulty, renders mild, efficient, environmentally friendly a formidable challenge. Herein, we develop visible-light-driven biocompatible arene C–H strategy with good efficiency regioselectivity, marvelous substrate applicability wide application scale-up synthesis, total late-stage functionalization. A nitryl radical delivered through unusual β-homolysis photoexcited ferric-nitrate complex proposed to be key nitrification reagent this system.

Although C–H bond functionalization has been extensively studied since its discovery in 1955, the borylation of organic compounds by activating bonds only became popular valuable Hartwig 1995 who considered a wider application these transformations synthetic chemistry. For borylation, catalytic activation this generally low-reactivity can be performed many ways. Among approaches reported are use and stoichiometric reagents, thermal activation, photochemical suitable substrates. Iridium-, ruthenium-, rhodium-based protocols using have played crucial role toward establishment area. Photochemical though, scarcely explored despite fact that it represents comparably environmentally benign protocol light as renewable energy source. In literature survey, we highlight recent developments from initial inception up to latest advancements.

Abstract Highly selective catalytic C(sp 3 )−H borylation of methoxy groups has been achieved using newly synthesized iron complexes bearing benzene‐based PCP‐type pincer ligands as catalysts. Reactions various aryl and alkyl methyl ethers substrates with bis(pinacolato)diboron under mild reaction conditions proceeded to afford the corresponding borylated products in good high yields. A successful example iron‐catalyzed a methylene group tetrahydrofuran (THF) was also presented. plausible pathway is proposed based on experimental result some stoichiometric reactions DFT calculations model reaction, where iron‐boryl ‐alkyl may work key intermediates.
