Liu, Xin published the artcilePillared Metal-Organic Framework Initiating Intermolecular Atom-Transfer Radical Addition via Visible-Light-Induced Electron Transfer Activation of Haloalkanes, Recommanded Product: Ethylbromofluoroacetate, the publication is ACS Applied Materials & Interfaces (2021), 13(29), 34114-34123, database is CAplus and MEDLINE.

Herein, a novel metal-organic framework (MOF) with a pillared-layer structure was rationally synthesized to initiate intermol. atom-transfer radical addition (ATRA) via photoinduced electron transfer activation of haloalkanes. The MOF synthesized via the controllable pillared-layer method is of excellent visible-light absorption and high chem. stability. Photocatalytic experiments show the atom transfer of various alkyl halides (R-X, X = Cl/Br/I) onto diverse olefins was successfully achieved to produce functional ATRA products. The mechanism and exptl. investigations reveal the prepared MOF serves as an efficient photocatalyst with strong reduction potential to activate haloalkane substrates via photoinduced electron transfer, generating a highly reactive alkyl radical to trigger the ATRA reaction. Key events in the ATRA reaction, including alkyl radical photogeneration as well as halide transfer, have been further regulated to achieve preferable photocatalytic performance with higher yields, shorter reaction time, and desirable cycling capability. It is notable that the work is the first report on photoinduced electron transfer activation of halides by a MOF photocatalyst for the ATRA reaction, providing a new blueprint for MOFs to develop photoinduced radical reactions.

Herein, synthesis of phenyl-(pyrimidinyloxyphenyl)butanoates I [R¹ = H, Me, Cl, etc.; R² = H, Me, F, etc; R³ = Me, F; R⁴ = Ph, 4-FC₆H₄, 4-BrC₆H₄, etc.; R² = R³ = Me, F; R⁵ = OEt, piperidin-1-yl, N(n-Bu)₂] via three-component ruthenium catalyzed C-H alkylation of phenoxypyrimidines and vinylbenzene and ethyl-bromo-difluoroacetates/alkyl bromides was reported. This strategy exhibited good substrates suitability and functional group tolerance with various phenol derivatives, which provided a synthetic potential drug approach. Mechanistic studies showed that a radical process might be involved in this process. In addition, the meta alkylated phenol was obtained by further removal of the directing group.

Tang, Wei-Ke published the artcileVisible-Light-Enabled Decarboxylative Mono- and Difluoromethylation of Cinnamic Acids under Metal-Free Conditions, Category: bromides-buliding-blocks, the publication is Organic Letters (2017), 19(20), 5501-5504, database is CAplus and MEDLINE.

Several new mono- and difluoromethylation reactions of cinnamic acids using an Eosin Y catalytic system are reported. An efficient alkene fluoromethylation of α,β-unsaturated carboxylic acids, e.g., I, II, and III, was accomplished under ambient temperature and metal-free conditions, with a wide range of functional group tolerance. A mechanism that involves a radical process is proposed for this reaction.

Riente, Paola published the artcileShedding light on the nature of the catalytically active species in photocatalytic reactions using Bi₂O₃ semiconductor, COA of Formula: C4H6BrFO2, the publication is Nature Communications (2021), 12(1), 625, database is CAplus and MEDLINE.

The importance of discovering the true catalytically active species involved in photocatalytic systems allows for a better and more general understanding of photocatalytic processes, which eventually may help to improve their efficiency. Bi₂O₃ has been used as a heterogeneous photocatalyst and is able to catalyze several synthetically important visible-light-driven organic transformations. However, insight into the operative catalyst involved in the photocatalytic process is hitherto missing. Herein, we show through a combination of theor. and exptl. studies that the perceived heterogeneous photocatalysis with Bi₂O₃ in the presence of alkyl bromides involves a homogeneous BinBrm species, which is the true photocatalyst operative in the reaction. Hence, Bi₂O₃ can be regarded as a precatalyst which is slowly converted in an active homogeneous photocatalyst. This work can also be of importance to mechanistic studies involving other semiconductor-based photocatalytic processes.

Granados, Albert published the artcileFrom Styrenes to Fluorinated Benzyl Bromides: A Photoinduced Difunctionalization via Atom Transfer Radical Addition, Product Details of C4H6BrFO2, the publication is Organic Letters (2022), 24(26), 4750-4755, database is CAplus and MEDLINE.

An operationally simple and practical method is disclosed to achieve the difunctionalization of styrenes RCH=CH₂ (R = Ph, 2-chlorophenyl, 1-benzothiophen-6-yl, etc.), generating fluorinated benzyl bromides RCH(Br)CH₂C(F)(R¹)C(O)R² (R¹ = H, F; R² = OEt, NEt₂) via a photoinduced atom transfer radical addition process. The developed method is mild, atom-economical, and cost-effective, employs very low photocatalyst loading (1000 ppm), and is highly compatible with a broad range of functional groups on styrene. The versatility of the fluorinated benzyl bromides is demonstrated through their derivatization to a variety of valuable compounds
