Lee, Sumin;Rovis, Tomislav research published 《 Rh(III)-Catalyzed Three-Component Syn-Carboamination of Alkenes Using Arylboronic Acids and Dioxazolones》, the research content is summarized as follows. A Rh(III)-catalyzed three-component carboamination of alkenes, e.g., 1,4-dihydro-1,4-epoxynaphthalene from readily available aryl boronic acids R¹B(OH)₂ (R¹ = C₆H₅, 1-naphthyl, 2H-1,3-benzodioxol-5-yl, etc.) as a carbon source and dioxazolones I (R² = CH₃, cyclopropyl, 2-cyclohexylethyl, etc.) as nitrogen electrophiles is described. This protocol provides facile access to valuable amine products including α-amino acid derivatives, e.g., II in good yield and regioselectivity without the need for a directing functionality. A series of experiments suggest a mechanism in which the Rh(III) catalyst undergoes transmetalation with the aryl boronic acid, followed by turnover limiting alkene migratory insertion into the Rh(III)-aryl bond. Subsequently, fast Rh-nitrene formation provides the syn-carboamination product selectively after reductive elimination and proto-demetalation. Importantly, the protocol provides three-component coupling products in preference to a variety of two-component undesired byproducts.

Le, Hong Tho;Goto, Atsushi research published 《 Halogen-bond-driven supramolecular assemblies of quaternary-ammonium-iodide-containing polymers in three phases》, the research content is summarized as follows. Halogen bonding (XB) opens avenues to supramol. assemblies. Here, the authors report XB-driven supramol. assemblies of quaternary ammonium iodide (QAI)-containing polymers in three (solution, surface, and solid) phases. In the solution, QAI-containing block copolymers form unique self-assembly structures such as micrometer-sized giant vesicles (up to 5-μm diameter) and a 1-dimensional (1D) structure with multiple inter-vesicular linkages via XB. Exploiting the temperature dependence of XB strength, external mols. are successfully loaded and unloaded. On the surface, reversible XB crosslinking and decrosslinking of QAI-containing polymer brushes are achieved. The wettability of the polymer brush is finely tuned by the XB crosslinking d. In solid phase, QAI-containing monomers are co-crystallized (assembled) via XB. A polymer sheet is obtained via the solid-phase polymerization of the monomer co-crystal; the sheet enables capture and release of halogen-containing (XB-coordinating) guest mols. and thereby serves as an innovative host material.

Le Vaillant, Franck;Mateos Calbet, Ana;Gonzalez-Pelayo, Silvia;Reijerse, Edward J.;Ni, Shengyang;Busch, Julia;Cornella, Josep research published 《 Catalytic synthesis of phenols with nitrous oxide》, the research content is summarized as follows. Here, an insertion of N₂O into a Ni-C bond under mild conditions (room temperature, 1.5-2 bar N₂O) for delivering valuable phenols ROH (R = Ph, 4-cyanophenyl, 1-oxo-2,3-dihydro-1H-inden-4-yl, quinolin-6-yl, etc.) and releasing benign N₂ was reported. This fundamentally distinct organometallic C-O bond-forming step differs from the current strategies based on reductive elimination and enables an alternative catalytic approach for the conversion of aryl halides RX (X = I, Br) to phenols. The process was rendered catalytic by means of a bipyridine-based ligands for the Ni center. The method is robust, mild and highly selective, and able to accommodate base-sensitive functionalities as well as permitting phenol synthesis from densely functionalized aryl halides. Although this protocol does not provide a solution to the mitigation of N₂O emissions, it represents a reactivity blueprint for the mild revalorization of abundant N₂O as an O source.
