A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling

Chemistry – A European Journal, EarlyView.
A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.

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 ...
