D’Agostini, Agnese; D’Auria, Maurizio published the artcile< Photochemical coupling between halogenoheterocyclic and heterocyclic derivatives>, COA of Formula: C6H5IO2S, the main research area is photochem coupling aryl aryl haloheterocycle heterocycle; iodothiophene iodofuran photochem coupling acetoxyallylthiophene acetoxyallylfuran.

The photochem. reaction between 5-iodo-heteroaryl derivatives I (X = O, R = H; X = S, R = Me, H, OMe) and both 3-heteroaryl allylic alcs. II (Y = O, S, R1 = H) and acetates II (Y = O, S, R1 = Ac) have been investigated. The presence of an alc. function was not compatible with photochem. coupling since compounds I were photoreduced in the presence of an alc. In contrast, the acetates gave the expected coupling products III (same X, Y, R, mixture of E and Z isomers). The presence of a weak electron-withdrawing group on the alkene induced an inverted regiochem. giving only aryl-aryl coupling products. The same behavior was observed using 2-(3-acetoxyprop-1-ynyl)thiophene, in which case only the product derived from aryl-aryl coupling was again observed When 2-prop-1-ynylthiophene was used as starting material, the product resulting from attack on the Me group was also observed Photochem. coupling between 2-thienylacetonitrile and halothienyl derivatives I (X = S, R = Me, H) gave no reaction product. In contrast, the irradiation of Me 2-thienylacetate and Me 2-(2-thienyl)propionate in the presence of I (X = S, R = Me, H) did give the corresponding aryl-aryl coupling products.

Wang, Lei; Byun, Jeehye; Li, Run; Huang, Wei; Zhang, Kai A. I. published the artcile< Molecular Design of Donor-Acceptor-Type Organic Photocatalysts for Metal-free Aromatic C-C Bond Formations under Visible Light>, Application of C7H3FIN, the main research area is mol Donor Acceptor organic photocatalysts metal free aromatic carbon.

Metal-free and photocatalytic radical-mediated aromatic C-C bond formations offer a promising alternative pathway to the conventional transition metal-catalyzed cross-coupling reactions. However, the formation of aryl radicals from common precursors such as aryl halides is highly challenging due to their extremely high reductive potential. Here, we report a structural design strategy of donor-acceptor-type organic photocatalysts for visible light-driven C-C bond formations through the reductive dehalogenation of aryl halides. The reduction potential of the photocatalysts could be systematically aligned to be -2.04 V vs. SCE via a simple heteroatom engineering of the donor-acceptor moieties. The high reductive potential of the mol. photocatalyst could reduce various aryl halides into aryl radicals to form the C-C bond with heteroarenes. The design ability of the mol. photocatalyst further allowed the synthesis of a high LUMO (LUMO) polymer photocatalyst by a self-initiated free radical polymerization without compromising its LUMO level.

The transition metal-catalyzed Mizoroki-Heck reaction is a powerful method to synthesize C-C bonds, allowing access to several important pharmaceuticals. Traditionally free amines have not been compatible with these approaches due to oxidation of the amine by the transition metal or other side reactions.

Herein, the palladium-catalyzed selective monoarylation of free allylamines using aryl iodides is reported. The strategy works on primary, secondary, and tertiary amines, making it very general. This monoarylation method is scalable and works on aryl iodides with a variety of substituted arene or heterocycle motifs, including chromophoric substrates.

Li, Jiafu;Aziz, Tareq Md.;Granger, Caroline O.;Richardson, Susan D. research published 《 Are Disinfection Byproducts (DBPs) Formed in My Cup of Tea? Regulated, Priority, and Unknown DBPs》, the research content is summarized as follows. Globally, tea is the second most consumed nonalcoholic beverage next to drinking water and is an important pathway of disinfection byproduct (DBP) exposure. When boiled tap water is used to brew tea, residual chlorine can produce DBPs by the reaction of chlorine with tea compounds In this study, 60 regulated and priority DBPs were measured in Twinings green tea, Earl Gray tea, and Lipton tea that was brewed using tap water or simulated tap water (nanopure water with chlorine). In many cases, measured DBP levels in tea were lower than in the tap water itself due to volatilization and sorption onto tea leaves. DBPs formed by the reaction of residual chlorine with tea precursors contributed ~12% of total DBPs in real tap water brewed tea, with the remaining 88% introduced by the tap water itself. Of that 12%, dichloroacetic acid, trichloroacetic acid, and chloroform were the only contributing DBPs. Total organic halogen in tea nearly doubled relative to tap water, with 96% of the halogenated DBPs unknown. Much of this unknown total organic halogen (TOX) may be high-mol.-weight haloarom. compounds, formed by the reaction of chlorine with polyphenols present in tea leaves. The identification of 15 haloarom. DBPs using gas chromatog.-high-resolution mass spectrometry indicates that this may be the case. Further studies on the identity and formation of these aromatic DBPs should be conducted since haloarom. DBPs can have significant toxicity.

This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.

2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.

Pd-catalyzed carbonylation, as an efficient synthetic approach for the installation of carbonyl groups in organic compounds, has been one of the most important research fields in the past decade. Although elegant reactions that allow highly selective carbonylations have been developed, straightforward routes with improved reaction activity and broader substrate scope remain long-term challenges for new practical applications. Here, authors show a new type of synergistic Cu/Pd-catalyzed carbonylation reaction using alcs. and dioxgen as the carbonyl sources. A broad range of aryl iodides and alcs. are compatible with this protocol. The reaction is concise and practical due to the ready availability of the starting materials and the scalability of the reaction. In addition, the reaction affords lactones and lactams in an intermol. fashion. Moreover, DFT calculations have been performed to study the detailed mechanisms.

Modular free-assembly construction of mono-, di-, and tri-fluoromethyl sulfones was comprehensively achieved by a combination of halides, a sulfur dioxide surrogate, and halofluorocarbons. The industrial raw material thiourea dioxide served as the sulfur dioxide source, combined with readily available fluorocarbon sources such as 2-bromo-2-fluoroacetate and chlorodifluoromethane employed as fluoromethyl reagents. Notably, four Me sulfone-containing pharmaceuticals were modified into three types of fluoromethyl sulfones, displaying their great potential for drug discovery via the current strategy. Mechanistic studies further demonstrated that C-F···H-N interactions between thiourea dioxide and halofluorocarbons play a key role in stabilizing monofluoromethyl electrophiles and difluorocarbene species.
