An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations
Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Correlation Analysis of Rate Constants for Dechlorination by Zero-Valent Iron
, 2016 Dehalogenation is among the most important processes involved in contaminant fate, but despite all the work that has been done on the kinetics of dehalogenation, there are few linear free energy relationships (LFERs) that can be used to explain or ...

Angewandte Chemie, Volume 136, Issue 48, November 25, 2024.We explore the difference between enantiomeric excess (ee) and relative Gibbs free activation energies (ΔΔG≠) as modeling targets in asymmetric catalysis. Through data analysis and application of modern machine learning methods, we unveil the strengths and limitations of each approach.

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles
European Journal of Organic Chemistry, EarlyView.Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...

Substituent Effects on Cyanine Dyes Vary with Position and Chain Length
Advanced Optical Materials, Volume 14, Issue 19, 22 May 2026.In cyanines, substituent effects vary as a function of substituent position and cyanine length. Electron‐donating‐ and ‐withdrawing groups at meso‐ and α‐positions of 4n+1/4n−1 long cyanines (n = 1, 2, 3…) cause opposing, hypsochromic and bathochromic shifts of the 1st UV–vis absorption bands.

Experimental and computational studies of fatty acid distribution networks [PDF]
, 2015 [Abstract] Unbalanced uptake of Omega 6/Omega 3 (ω-6/ω-3) ratios could increase chronic disease occurrences, such as inflammation, atherosclerosis, or tumor proliferation, and methylation methods for measuring the ruminal microbiome fatty acid (FA ...
