Impact of Monomer Purity on the Acid‐Catalyzed ROP of Sarcosine N‐Carboxyanhydrides: A Comparative Study of Phosgene‐Free Synthetic Routes toward High‐Molecular‐Weight Polysarcosine

Macromolecular Rapid Communications, EarlyView.
A robust, phosgene‐free oxalyl chloride/silyl‐mediated route yields high‐purity sarcosine N‐carboxyanhydride (Sar‐NCA) by eliminating residual impurities that compromise polymerization control. This strategy enables well‐defined, acid‐catalyzed ring‐opening polymerization under ambient conditions, producing polysarcosine with Mn up to 186 kDa and ...

Electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines under mild conditions with a proton-exchange membrane reactor

Beilstein Journal of Organic Chemistry
An electrocatalytic hydrogenation of cyanoarenes, nitroarenes, quinolines, and pyridines using a proton-exchange membrane (PEM) reactor was developed. Cyanoarenes were then reduced to the corresponding benzylamines at room temperature in the presence of ...

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 ...

Isotope effects reveal that para-substituted benzylamines are poor reactivity probes of the quinoprotein mechanism for aromatic amine dehydrogenase

, 2007
Structure-activity correlations have been employed previously in the mechanistic interpretation of TTQ-dependent amine dehydrogenases using a series of para-substituted benzylamines.

Polyoxometalate‐Scaffolded Perylene Diimide Dimers: Preorganization and Dynamic Charge Regulation for Enhanced and Durable Photosensitization

Small, EarlyView.
Polyoxometalate scaffolds simultaneously structurally preorganize perylene diimide dimers for ultrafast excimer formation and regulate excited‐state charge dynamics through intramolecular charge buffering, enabling efficient durable photosensitization for singlet oxygen generation.
