Infrared Irradiation‐Assisted Pd‐Catalyzed C(sp3)─H Arylation and Tandem Cyclization of Ortho‐Tolualdehydes

Chemistry – A European Journal, EarlyView.
A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

Self‐Immolative Poly(Benzyl Ether)s: Design Principles and Controlled Depolymerization

Chemistry – A European Journal, EarlyView.
Unzipping to Sustainability: This Concept article explores the thermodynamic design of quinone‐methide (QM)‐based poly(benzyl ether)s (PBEs). It explains how a low ceiling temperature (Tc), QM stability, and an entropic gain drive rapid depolymerization (“unzipping”) of PBEs into monomers.

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

First Occurrence of Fatal Intoxication Involving Methiodone (IC‐26) in Finland; a Medicolegal Autopsy Case Report

Drug Testing and Analysis, EarlyView.
ABSTRACT Methiodone (IC‐26) is a non‐fentanyl novel synthetic opioid which has recently been detected in drug seizures in Europe. There is still limited data about the drug in published toxicological case work, both in non‐fatal and fatal cases. We present a medicolegal autopsy case report on a fatal intoxication in an individual undergoing opioid ...

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Edged Donor–Acceptor Engineering in Conjugated Organic Polymers for Cocatalyst‐Free Photocatalytic H2 Evolution

EcoEnergy, EarlyView.
A terminal donor–acceptor pair is constructed at the edge of sulfone‐based conjugated polymers to establish intramolecular charge transfer paths. This design activates dual‐role active sites for proton adsorption and electron acceptance, achieving efficient cocatalyst‐free photocatalytic hydrogen evolution through optimized kinetics and tunable D‐A ...
