چکیده

Exposure of the uranium(IV) complex, Cp(P)U((Mes)PDI(Me)) (1) ((Mes)PDI(Me) = 2,6-((Mes)N=CMe)2–C5H3N; Mes = 2,4,6-trimethylphenyl; Cp(P) = 1-(7,7-dimethylbenzyl)cyclopentadienyl), which contains a [(Mes)PDI(Me)](3−) chelate, to I2, Cl2, PhSeCl, and PhEEPh (E = S, Se, Te) results in oxidative addition to form the uranium(IV) family, Cp(P)U(XX′)((Mes)PDI(Me)) (X = X′ = I, Cl, EPh; X = SePh, X′ = Cl). Spectroscopic and structural studies support products with [(Mes)PDI(Me)](1−), indicating the reducing equivalents derive from this redox-active chelate.

Computational insights into uranium complexes supported by redox-active α-diimine ligands.

The electronic structures of two uranium compounds supported by redox-active α-diimine ligands, ((Mes)DAB(Me))(2)U(THF) (1) and Cp(2)U((Mes)DAB(Me)) (2) ((Mes)DAB(Me) = [ArN═C(Me)C(Me)═NAr]; Ar = 2,4,6-trimethylphenyl (Mes)), have been investigated using both density functional theory and multiconfigurational self-consistent field methods. Results from these studies have established that both u...

Multi-electron reduction facilitated by a trianionic pyridine(diimine) ligand.

Reduction of Cp*2UI(THF) with KC8 in the presence of a pyridine(diimine) ligand ((Mes)PDI(Me)) results in the formation of Cp*U(PDI)(THF), which features a triply reduced PDI ligand. This species performs four electron cleavage of azobenzene to generate the uranium bis(imido), Cp*(PDI)U(NPh)2.

Lysosomal Oxidative Stress Cytotoxicity Induced By Para-phenylenediamine Redox Cycling In Hepatocytes

It has already been reported that muscle necrosis induced by various phenylenediamine derivatives are correlated with their autoxidation rate. Now in a more detailed investigation of the cytotoxic mechanism using a model system of isolated hepatocytes and ring-methylated structural isomer durenediamine (DD) we have shown that under aerobic conditions, phenylenediamine induced cytotoxicity and R...

Uranium-mediated oxidative addition and reductive elimination.

Oxidative addition, and its reverse reaction reductive elimination, constitute two key reactions that underpin organometallic chemistry and catalysis. Although these reactions have been known for decades in main group and transition metal systems, they are exceptionally rare or unknown for the f-block. However, in recent years much progress has been made. In this Perspective article, advances i...
