Reactions of a Uranium(III) Complex with N-Heterocycles to Form Diuranium(IV) Ketimides

The chemistry of the classical uranium(III) complex [U(N″)3] (N″ = {N(SiMe3)2}−) is well-developed; however, there have been surprisingly few studies of its reactivity toward N-heterocycles. Here, we ...

Reactions of a uranium(III) complex with N-heterocycles to form diuranium(IV) ketimides | ChemRxiv

The chemistry of the classical uranium(III) complex [U(N′′)3] (N′′ = {N(SiMe3)2}–) is well-developed, but there have been surprisingly few studies of its reactivity towards N-heterocycles. Here we report the separate reactions of [U(N′′)3] with pyrazine, ...

Uranocenium – The bis-[8]annulene Uranium Cation | ChemRxiv

Uranocene, [UIV(η8-C8H8)2], is the actinide equivalent to ferrocene. While ferrocene is readily oxidised to the ferrocenium cation, higher oxidation states of uranocene are unknown. Here we report the elusive uranocenium cation, [UV(η8-C8H8)2]+ , and ...
