Mechanical reinforcement and memory effect of strain-induced soft segment crystals in thermoplastic polyurethane-urea elastomers

Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot

An amorphous poly(urethane-urea) copolymer composed of 70 wt% poly(ethylene oxide) (PEO) soft segments (SS) (Mw = 2000 g mol−1) and 30 wt% cycloaliphatic hard segments (HS) was subjected to in-situ X-Rays during tensile deformation. Mechanical hardening at ...

Alkynyl Triazenes as Fluoroalkyne Surrogates: Regioselective Access to 4-Fluoro-2-pyridones by a Rh(III)-Catalyzed C–H Activation–Lossen Rearrangement–Wallach Reaction

Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Jin Fay Tan

Fluorinated pyridones are an important scaffold displaying relevant biological activities. Efficient assembly strategies of pyridones are transition metal-catalyzed C–H annulations with alkynes. The inaccessibility and extreme lability of fluoro alkynes re ...

En route to CO2-containing renewable materials: catalytic synthesis of polycarbonates and non-isocyanate polyhydroxyurethanes derived from cyclic carbonates

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden

Combining CO2-chemistry with biomass conversion allows renewable polymeric materials including polycarbonates and polyhydroxyurethanes (PHUs) to be generated. The demand for robust materials with modular properties that can be prepared on an industrial sca ...

To each his own: isonitriles for all flavors. Functionalized isocyanides as valuable tools in organic synthesis

Jieping Zhu, Andrea Basso

The term functionalized isocyanides refers to all those isocyanides in which a neighbouring functional group can finely tune the reactivity of the isocyano group or can be exploited in post-functionalization processes. In this manuscript, we have reviewed ...

Effect of Very High Charge Density and Monomer Constitution on the Synthesis and Properties of Cationic Polyelectrolytes

Jutta Christine Wandrey, Ricardo Losada Mateo, Hamideh Ahmadloo

The free-radical homopolymerization of 1,3-bis(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and 1,3-bis(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A) in aqueous solution yields cationic polyelectrolytes (PEL) with theoretic ...

CO2 conversion to isocyanate via multiple N–Si bond cleavage at a bulky uranium(III) complex

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reaction of the sterically saturated uranium(III) tetrasilylamido complex [K(18c6)][U(N(SiMe3)(2))(4)] with CO2 leads to CO2 insertion into the U-N bond affording the stable U(IV) isocyanate complex [K(18c6)]U(N(SiMe3)(2))(3)(NCO)(2) that was crys ...

Continuous Polyol Synthesis of Metal and Metal Oxide Nanoparticles Using a Segmented Flow Tubular Reactor (SFTR)

Paul Bowen, Andrea Testino, Christoph Stähli, Jose Enrico Quijano Quinsaat, Frank Pilger

Over the last years a new type of tubular plug flow reactor, the segmented flow tubular reactor (SFTR), has proven its versatility and robustness through the water-based synthesis of precipitates as varied as CaCO3, BaTiO3, Mn((1-x))Ni(x)C(2)O(4)2H(2)O, YB ...

Suzuki-Miyaura Cross-Coupling Reactions of Unactivated Alkyl Halides Catalyzed by a Nickel Pincer Complex

Xile Hu, Thomas Clément Di Franco, Nicolas Francis Michel Boutin

A nickel(II) pincer complex, [((N2N)-N-Me)Ni-Cl], was used to catalyze alkyl-alkyl and alkyl-aryl Suzuki-Miyaura coupling reactions of unactivated alkyl halides. The coupling of 9-alkyl-9-borabicyclo[3.3.1]nonane and 9-phenyl-9-borabicyclo[3.3.1]nonane rea ...
