Summary: We have developed a method for converting esters to ketones in a single step using simple reagents. This selective transformation is achieved by activating the adjacent carbon to deprotonation through the use of a transient sulfinate group on the nucleophile, allowing the formation of a carbanion that adds to the ester. This reaction is then followed by another deprotonation step to prevent further addition, and the resulting dianion spontaneously fragments the SO2 group upon quenching with water to produce the ketone product.

Summary: A base-promoted protocol was investigated for the intermolecular anti-Markovnikov hydroamidation of vinyl arenes, leading to the formation of arylethylbenzamides with excellent chemo- and regioselectivity. The reaction demonstrated high chemoselectivity for the amide group over amine and tolerance towards a wide variety of functional groups. The proposed mechanism and the importance of the solvent were supported by deuterium labeling studies and control experiments.

Summary: The synthesis of highly functionalized chiral 3-pyrrolines is important for the production of natural and synthetic bioactive molecules. Previous methods using allenoates could not synthesize 3,4-disubstituted 3-pyrrolines. This study presents a novel approach to produce 2,3,4-trisubstituted chiral 3-pyrrolines through a highly stereoselective process using a Ni-II/Fc-i-PrPHOX catalytic system.

Summary: Inorganic clusters, specifically polyoxometalates (POMs), can serve as effective ligands for Hf(IV) Lewis acid metals in homogeneous metal catalysis. The interplay between the dielectric constant of the medium and the ligand structure is crucial for optimizing catalytic activity and promoting efficient amide bond formation. Changes in the dielectric constant can significantly impact the performance of the catalyst, highlighting the importance of understanding the relationship between medium properties and catalyst reactivity.

Summary: Novel ferrocene-based PNN ligands were prepared and found to be highly effective catalysts for the homogeneous hydrogenation of cyclic imides with iridium (TON up to 50,000). The hydrogenation mode could be finely tuned by tiny changes in the ligands, leading to high yields of a variety of omega-hydroxylactams and omega-hydroxyamides with different functional groups.

Summary: 2-butenylquinazolin-4(3H)-ones can undergo intramolecular aza-Wacker cyclization to form methylene-substituted pyrrolo(pyrido)[2,1-b]quinazolinones when treated with the catalytic system Pd(OAc)(2)/PPh3/Cs2CO3/benzoquinone in dioxane or Pd(PPh3)(2)Cl-2/t-BuONa/Cs2CO3/benzoquinone in toluene. The latter catalytic system also reacts with pentenyl(hexenyl)quinazolin-4(3H)-ones, but leads to the formation of vinyl-substituted pyrrolo(pyrido)[2,1-b]quinazolinones via competition between aminopalladation of C-H multiple bonds and allylic C(sp(3))-H bond activation.

The reaction showed smooth progress with exclusive Markovnikov regioselectivity, providing easy access to a range of branched secondary alkyl boronic esters in moderate to excellent yields. The solvent was demonstrated to be the source of hydrogen, as confirmed by the deuterium experiments.

Summary: We report a simple and efficient method for the selective C-H bond insertion of copper carbenes generated in situ from 4-diazo-1,4-dihydroisoquinolin-3-ones into beta-C(sp(2))-H bonds of N-sulfonyl enamides. This reaction yields a series of 4-(1,4,5,6-tetrahydropyridin-3-yl)-1,4-dihydroisoquinolin-3(2H)-ones with good to excellent yields. The reaction benefits from its simple and mild reaction conditions, the use of a cheap catalyst, readily accessible starting materials, and a broad substrate scope.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.
