A High Energy Barrier DyIII2 Single‐Molecule Magnet Supported by a Bulky, Anionic N–O Bridging Ligand

Chemistry – A European Journal, EarlyView.
Complex [Dy2(hynad)2(dbm)4] was prepared by the employment of the anionic N–O‐based bridging and chelating N‐hydroxy‐1,8‐naphthalimide ligand, featuring a {Dy2(µ‐OR)2}4+ core and exhibiting zero‐field SMM behavior with a Ueff value of 171 K and double‐S‐shaped hysteresis loops, open up to 3.5 K.

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.

[Ti(py)4I2] as an Entry Point to Titanium(II) Chemistry via Titanium Metal Oxidation

Chemistry – A European Journal, EarlyView.
A strategically novel approach based on the oxidation of Ti metal enables access to Ti(II) chemistry. Controlled formation and complexation of Ti diiodide affords the Ti(II) complex [Ti(py)4I2], which serves as a convenient entry point to Ti(II) compounds.

H2O2 Activation and Alkane Oxidation by Copper Complexes With R‐dpa N3‐Tridentate Ligands: The Complex‐Based Dicopper Active Species as a Key Feature in the Efficient Alkane Oxidation

Chemistry – A European Journal, EarlyView.
Two reaction pathways, Paths 1 and 2, are involved in H2O2 activation by Cu complexes with N3‐tridentate ligands, depending on the ease of bridging structure formation. In Path 1, hydroxy radical (HO•) is formed from a hydroperoxo Cu(II) intermediate. In Path 2, a relevant complex‐based μ‐O• bridged Cu(II)2 active species is formed from a bis‐μ‐oxo Cu ...
