The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Multistep Changes in Spin‐Crossover Temperature Induced by Stepwise Desolvations

Chemistry – A European Journal, EarlyView.
A novel Fe(II) complex (1·3VN) exhibits SCO behavior in which the spin transition temperature sequentially increases and then decreases by stepwise removal of valeronitrile (VN) molecules. These non‐monotonic changes in the transition temperature are explained by the changes in intermolecular interactions among the Fe complex and each valeronitrile ...

Experimental methods in chemical engineering: Magnetometry

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

A Self‐Enhanced Tandem Catalytic System for Olefin‐to‐Diol Conversion Powered by Single‐Atom Fe Catalysts With In Situ Generated Acid

EcoEnergy, EarlyView.
A single‐atom iron catalyst with well‐defined Fe–N4 sites enables a tandem epoxidation‐hydrolysis process for converting terminal olefins to 1,2‐diols. The in situ‐generated isobutyric acid drives the hydrolysis step, affording broad substrate scope and excellent recyclability.
