[2 + 2 + 2] cycloaddition of a 1,2-bis(propiolyl)benzene derivative with terminal and internal alkynes takes place in the presence of [Ir(cod)Cl]2 (cod = 1,5-cyclooctadiene) combined with bis(diphenylphosphino)ethane (DPPE) to give anthraquinones in 42 ...

Synthesis and Optical Properties of Diboron Complexes of 1,4-Anthraquinone Derivatives. [PDF]
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...

Characterization of the Interaction of Known G‐quadruplex Ligands With a Minimal i‐Motif Structure
The destabilization of a minimal i‐Motif (iM) structure by TMPyP4 is driven by ligand recognition of one terminal iM structural domain. ABSTRACT Peculiar genomic regions are prone to evolve transiently from double‐helix DNA to noncanonical secondary structures in response to physiological stress.

A new silver‐catalyzed H/D exchange reaction was developed for the labelling of quinones and related compounds. Both homogeneous and heterogeneous catalytic processes were implemented using heavy water as a simple deuterium source. The corresponding deuterated compounds were obtained with high isotopic enrichment through a practical method that opens ...

A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

Decolorization of Disperse Dyes in Textile Polyester Recycling Using Activated Carbon
Decolorization of disperse dyes from disodium terephthalate solutions is examined using two activated carbons with varying pore structures and surface properties. The potential impact of pore size distribution and surface charge on the adsorption process is assessed to support optimized adsorbent selection.
