Highly Tunable Thermal Properties of Multifunctional Thiol‐Ene Networks Derived From Sugar‐Based Monomers

Journal of Polymer Science, EarlyView.
Eleven allylated sugar frameworks combined with seven dithiol compounds create 77 thiol‐ene networks with a wide range of thermomechanical properties. Analysis based on composition reveals that both the sugar's functionality and the scaffold's structure work in conjunction with dithiol chemistry to influence the rubbery modulus, glass‐transition ...

Condensing the Cage: Novel Insights Into the Reaction Pathway of Isowurtzitane Cage Formation

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT In this contribution, we propose an alternative reaction pathway for the formation of isowurtzitane cages. These cage products are the basis for the synthesis of CL‐20, a highly prized energetic material and propellant. Isowurtzitane cages are typically formed under acid‐catalysed conditions via the condensation reaction between glyoxal and ...

Isolated Organosodium and ‐Potassium Intermediates: Understanding Metal Effects on Anionic Styrene‐Isoprene Copolymerization

Small, EarlyView.
Reactive organosodium and organopotassium intermediates of the anionic styrene and isoprene polymerization are presented. Crystal structures of alkoxide‐free intermediates are obtained by X‐ray diffraction, and their isolation enables kinetic polymerization studies.

Modular Synthesis of α‐Quaternary Pyrrolines by Pyridoxal‐Catalyzed Sequential Reactions With Precise Chirality Relay

Transformative Chemistry, EarlyView.
Direct asymmetric α‐C conjugate addition of aminoacetonitrile enabled by carbonyl/iminium double activation, together with subsequent electrophilic functionalization, offers a one‐pot, two‐step modular strategy for synthesizing chiral α‐quaternary pyrrolines with precise chirality relay and high structural diversity.

Electrochemical Reductive β‐Arylation and Alkenylation of α‐Branched Acroleins by Primary Amine/Nickel Dual Catalysis

Transformative Chemistry, EarlyView.
A synergistic primary amine/nickel catalysis under electrochemical conditions was developed for cathodic β‐arylation and alkenylation of α‐branched acroleins. The reaction proceeds through β‐enaminyl radicals generated by cathodic reduction of an iminium ion allowing smooth coupling with aryl‐ or alkenyl‐Ni(II) species.
