Single-Determinant Ground State in Ce <sup>4+</sup> Imidophosphorane Complexes Open
X-ray spectroscopy techniques are critical in the electronic structure analysis of high-valent lanthanides. The interpretation of multipeaked features at the lanthanide L3-edge has remained a challenging question, as it is observed across …

Photo-Triggerable Polymerization and Depolymerization of Stiff-Stilbene Lactones Open
The development of photoswitchable polymers has unlocked new avenues for controlling polymerization and depolymerization through external stimuli. In this work, we introduce a strategy that integrates stiff-stilbene-based cyclic monomers w…

Bis(<i>tert</i>-butoxydiphenylsilyl)amide Divalent Lanthanide Complexes Open
The development of new ligand systems to stabilize "non-traditional/non-classical" divalent lanthanides is key to tuning the chemical and physical properties of their mixed principal quantum number 4fn5d1 ground states. The design and stud…

Redox-Active Ligands Permit Multielectron O<sub>2</sub> Homolysis and O-Atom Transfer at Exceptionally High-Valent Vanadyl Complexes Open
A five-coordinate chlorovanadium species supported by two redox-active N-phenyl aminophenol ligands was prepared. Experimental and computational data support formulation of this complex as [(Phap)(Phisq)VIVCl], containing one dianionic [Ph…

Michael Addition–Elimination Ring-Opening Polymerization Open
A cyclic thioenone system capable of controlled ring-opening polymerization (ROP) is presented that leverages a reversible Michael addition-elimination (MAE) mechanism. The cyclic thioenone monomers are easy to access and modify and for th…

Tetravalent Cerium Alkyl and Benzyl Complexes Open
High-valent cerium complexes of alkyl and benzyl ligands are unprecedented due to the incompatibility of the typically highly oxidizing Ce4+ ion and the reducing alkyl or benzyl ligand. Herein we report the synthesis and isolation of the f…

A Tetrahedral Neptunium(V) Complex Open
Neptunium is an actinide element sourced from anthropogenic production, and unlike naturally abundant uranium, its coordination chemistry is not well-developed in all accessible oxidation states. High-valent neptunium generally requires st…

Divergent Stabilities of Tetravalent Cerium, Uranium, and Neptunium Imidophosphorane Complexes** Open
The study of the redox chemistry of mid‐actinides (U−Pu) has historically relied on cerium as a model, due to the accessibility of trivalent and tetravalent oxidation states for these ions. Recently, dramatic shifts of lanthanide 4+/3+ non…
