Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

Polymer International, Volume 75, Issue 8, Page 722-728, August 2026.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Photochemistry of N‐Substituted, N′‐Tosyl Diphenyl Sulfondiimines

Journal of Physical Organic Chemistry, Volume 39, Issue 8, August 2026.
The irradiation of N‐substituted, N′‐tosyl diphenyl sulfondiimines with UV light induces the sequential photorelease of two different nitrenes. ABSTRACT Sulfondiimines are an emerging sulfur(VI) functional group with increasing use in synthesis and medicinal chemistry, yet their photochemical behavior has remained largely unexplored.

Contact Sensitization in Patients With Frontal Fibrosing Alopecia: Patch Test Results With an Extended Baseline Series in Consecutive Patients

Contact Dermatitis, Volume 95, Issue 2, Page 192-199, August 2026.
Sensitization to propolis, shellac and gallate mix is FFA‐associated, but its relevance is largely unknown. Sensitization to salicylates is frequent and associated with symptoms of intolerance to sun exposure or sunscreens. No significant improvement by allergen avoidance is identified.

Hybrid Aminoferrocenes With Nitrate Esters for In Situ Peroxynitrite Generation: Complex Interplay Between Redox Chemistry, NO‐Donor Reactivity, and Aminoferrocene Activation Influences In Vitro Anticancer Activity

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Aminoferrocene‐based prodrugs represent a promising class of redox‐active anticancer agents that can be selectively activated in oxidative cellular environments. However, activation of these systems typically relies on reactive oxygen species (ROS) and is therefore inefficient in intracellular compartments with low ROS levels, such as the cytoplasm. In

Sustainable Synthesis of Bio‐Based Furanic and Aromatic Amines Using an Optimized Whole‐Cell Transaminase–Decarboxylase Cascade in E. coli RARE

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
A whole‐cell biocatalytic cascade in engineered Escherichia coli RARE couples the ω‐transaminase from Pseudomonas psychrotolerans with pyruvate decarboxylase from Zymomonas mobilis to shift transamination toward amine formation via pyruvate removal. Integration of the cascade into a chemo‐enzymatic synthesis pathway enables the scalable production of 2,

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

From SMILES Codes for Reactants and Products to Transition States With VeloxChem

Journal of Computational Chemistry, Volume 47, Issue 18, July 5, 2026.
Initial guesses for transition state optimizations are produced from a mere input of reactant and product SMILES codes, and achieved by interpolating generated force fields for reactants and products. The entire workflow scheme is implemented in the VeloxChem software.
