Kertsomboon, Thanit;Chirachanchai, Suwabun research published 《 Amphiphilic biodegradable co-networks of Poly(butylene succinate)-Poly(ethylene glycol) chains for nano-gelation via Click chemistry and its potential dispersant for multi-walled carbon nanotubes》, the research content is summarized as follows. Amphiphilic nanogel (APNG) is a class of material miscible with water and oil which is practical for active mols. incorporation, water-oil dispersion, etc. In general, preparation of APNGs requires multi-steps involving the copolymer with different hydrophilic units and the micelles formation to confine the nano-level for the crosslink. The present work proposes a simple way to prepare APNGs by applying the co-networks of biodegradable hydrophilic and hydrophobic chains. The co-networks between alkyno-poly(acrylic acid) (alkyno-PAA) and diazido-poly(ethylene glycol) (N₃-PEG-N₃) as well as diazido-poly(butylene succinate) (N₃-PBS-N₃) via copper-catalyzed azide-alkyne cycloaddition (CuAAC) Click lead to APNG. The variation of hydrophilic N₃-PEG-N₃ and hydrophobic N₃-PBS-N₃ controls the amphiphilicity as evidenced from the swelling performances in various solvents with different polarity. The APNG obtained favors multi-walled carbon nanotubes (MWCNTs) to be dispersed in water for weeks without precipitation suggesting a potential dispersant of MWCNTs in hydrophilic media, especially aqueous solution

Jouffroy, Matthieu;Nguyen, Thi-Mo;Cordier, Marie;Blot, Marielle;Roisnel, Thierry;Gramage-Doria, Rafael research published 《 Iridium-Catalyzed Direct Reductive Amination of Ketones and Secondary Amines: Breaking the Aliphatic Wall》, the research content is summarized as follows. Direct reductive amination (DRA) is a ubiquitous reaction in organic chem. This transformation between a carbonyl group and an amine is most often achieved by using a super stoichiometric amount of hazardous hydride reagents, thus being incompatible with many sensitive functional groups. DRA could also be achieved by means of chemo- or biocatalysis, thereby attracting the interest of industry as well as academic laboratories due to the virtually perfect atom economy. Although DRAs are well-established for substrate pairs such as aldehydes with either 1° or 2° amines as well as ketones with 1° amines, the current methodologies are limited in the case of ketones with 2° amines. Herein, a general DRA protocol that overcomes this major limitation by means of iridium catalysis is presented. The applicability of the methodol. is demonstrated by accessing an unprecedented range of biol. relevant tertiary amines starting from both aliphatic ketones and aliphatic amines. The choice of a disphosphane ligand (Josiphos A or Xantphos) is essential for the success of the transformation.
