Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 260-281, March/April 2026.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

Influence of the organic linker substituent on the catalytic activity of MIL-101(Cr) for the oxidative coupling of benzylamines to imines [PDF]

, 2017
[EN] MIL-101(Cr) having substituents at the terephthalate linker (X = H, NO2, SO3H, Cl, CH3 and NH2) promotes the aerobic oxidation of benzylamines to the corresponding N-benzylidene benzylamines at different rates.

Strain‐Release Diversification of 1‐Azabicyclobutanes via Bromide/Nickel Relay Catalyzed 1,3‐Bis‐Carbofunctionalization

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
A four‐component synthesis of azetidines with an all‐carbon quaternary center via strain‐release 1,3‐bis‐carbofunctionalization of 1‐azabicyclobutanes (ABB) is described. Each reaction component can be modified to permit a high‐throughput‐like library preparation, producing azetidines with various appendages, including biorelevant molecules.

Design, Synthesis, and Structural Evolution of Pseudo‐Natural Product IDO1 Inhibitors and Degraders

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The combination of bicyclic monoterpene‐ and pyrrolidine‐alkaloid fragments yields novel pseudo‐natural products. Biological characterization revealed that these iDegs are inhibitors and degraders of indoleamine‐2,3‐dioxygenase. Abstract Terpenoid alkaloids are derived from the fusion of structurally diverse terpenoid‐ and alkaloid moieties.

Tandem Takeoff: Powering Tomorrow with Industrial‐Grade Perovskite/Silicon Solar Cells

Advanced Energy Materials, Volume 16, Issue 5, 4 February 2026.
Perovskite/silicon tandem solar cells have recently achieved certified power conversion efficiencies of 34.85%, far exceeding the Shockley‐Queisser limit for single‐junction silicon and standalone perovskite cells. This review highlights the latest advances in the design, integration, and optimization of perovskite top cells for monolithic tandem ...

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, Volume 4, Issue 2, February 2026.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.
