Alkanes in Minisci-Type Reaction under Photocatalytic Conditions with Hydrogen Evolution

Organic Letters, Год журнала: 2023, Номер 25(48), С. 8541 - 8546

Опубликована: Окт. 11, 2023

We report herein a protocol for the selective activation of C(sp3)–H bonds based on interplay two readily available organic catalysts and their successful implementation in cross-coupling azaarenes with alkanes. This Minisci-like reaction is promoted by visible light at room temperature free from chemical oxidants, metals, chlorinated solvents. A wide range substrates are compatible, including some bioactive molecules. Mechanistic studies support dual catalytic cycle H2 evolution.

C(sp³)‐H Functionalization Using Chlorine Radicals

Advanced Synthesis & Catalysis, Год журнала: 2024, Номер 366(13), С. 2898 - 2918

Опубликована: Май 18, 2024

Abstract Converting any desired C−H bond to the intended C−Z in a given organic molecule could be final peak of functionalization methodology. Among three types bonds, ubiquitous C( sp 3 )−H has gained particular attention, especially last two decades. There are different ways transform bonds into bonds. The use chlorine radicals is one these methods with promising future. literature review shows that sources have been used for chlorine, including chloride ions (HCl or salts), coordinated chlorides (transition metal complexes), and (organochlorine compounds). However, HCl FeCl most attention among sources. major convert from radicals: 1) oxidation hydrogen salts, 2) photolysis chloride, 3) transition insertion C−Cl This summarizes published research papers on functionalization. Therefore, chlorination reactions which do not play direct role cleavage within scope this review.

Visible-Light-Promoted Deoxygenative Alkylation of Quinoxalin-2(1H)-ones with Activated Alcohols

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(9), С. 6334 - 6344

Опубликована: Апрель 15, 2024

A one-pot strategy for deoxygenative alkylation of alcohols with quinoxalin-2(1H)-ones was developed by using xanthate salts as alcohol-activating groups radical generation in the presence tricyclohexylphosphine under visible-light-promoted conditions. The remarkable features this reaction include a broad substrate scope, excellent functional group tolerance, mild conditions, and simple operation. Moreover, synthetic utility validated success two-step reactions, scale-up synthesis, chemoselective monodeoxygenation diols.

Iron Photocatalysis for C─H Functionalizations

Asian Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Май 26, 2025

Abstract Photo‐assisted, iron‐catalyzed C─H functionalizations represent nowadays a sustainable tool to develop unprecedented transformations, unviable by common catalytic organometallic approaches promoted transition metals. In fact, the use of this new technology allows for more efficient synthetic transformations increasing chemo‐, regio‐ and site‐selectivity catalysis while reducing formation by‐products shortening reaction times. Further, replacement precious transition‐metals with iron catalysts is highly desiderable development environmentally‐friendly methods. Within review, we aim summarize latest achievements combining most abundant safe metal in “outer‐sphere” functionalization reactions mediated light C─C C─Het bonds, including challenging C─N, C─P, C─B C─S bonds. Particular attention has been directed toward description mechanistic aspects application methods late‐stage polymers, marketed drugs, biologically‐active compounds materials.
