Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

Chemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

Chemistry – A European Journal, EarlyView.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.
