Reliable Identification and Out‐of‐Library Detection in Mass Spectra

Journal of Chemometrics, Volume 40, Issue 8, August 2026.
ABSTRACT Accurate molecular identification from mass spectra is essential in analytical workflows, yet conventional library search typically returns the closest match even when the true compound is absent, leading to overconfident false positives. We propose a probabilistic framework that supports both reliable identification of compounds represented ...

Electrochemical C─H Amination From a Primary Amine via a Cobalt Nitrene Intermediate

ChemistryEurope, Volume 4, Issue 8, August 2026.
This article reveals proof of principle to unlock the use of unfunctionalized amines as nitrene precursor alternatives, extending the applicability of metal nitrene transfer catalysis. Electrochemical generation of a cobalt nitrene intermediate from 4‐phenylbutylamine leads to C─H amination, producing the cyclic imine 2‐phenylpyrroline.

Diastereoselective Copper‐Catalyzed Defluorosilylation of Pentafluoroethyl Alkenes to Access Polyfluorinated Allylsilanes

Chinese Journal of Chemistry, Volume 44, Issue 15, Page 2587-2592, 1 August 2026.
Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.

Mechanochemistry as an Emerging Tool for Organofluorine Chemistry

Chemistry–Methods, Volume 6, Issue 8, August 2026.
Fluorinated scaffolds are central across many areas of chemistry, driving the demand for efficient and sustainable synthetic methods. Mechanochemistry has emerged as a powerful alternative to conventional approaches, offering reduced environmental impact, shorter reaction times, and unique reactivity and selectivity.
