The chemistry of f-block metal–carbon multiple bonds is underdeveloped compared to well-
established carbene complexes of the d-block transition metals. Herein, we report two new …

There is a growing interest in uranium coordination chemistry, particularly as it relates to
metal–ligand multiple bonding, and in the last decade significant progress has been made …

Abstract Supramolecular nanocapsule 1⋅(BArF) 8 is able to sequentially and selectively
entrap recently discovered U2@ C80 and unprecedented Sc2CU@ C80, simply by soaking …

A new generation of simple methylidene complexes has been prepared by reactions of
excited group 4− 6 transition metal atoms with methyl halides and methane in solid argon …

Unsupported non-bridged uranium–carbon double bonds have long been sought after in
actinide chemistry as fundamental synthetic targets in the study of actinide-ligand multiple …

The reaction of [AnCl (NR2) 3](An= U, Th, R= SiMe3) with in situ generated lithium-3, 3-
diphenylcyclopropene results in the formation of [{(NR2) 3} An (CHCCPh2)](An= U, 1; Th, 2) …

Dative bonds between p-and d-block atoms are common but species containing a double
dative bond, which donate two-electron pairs to the same acceptor, are far less common …

Despite the fact that non-aqueous uranium chemistry is over 60 years old, most polarised-
covalent uranium-element multiple bonds involve formal uranium oxidation states IV, V, and …

Reaction of the Th (IV) metallacycle [Th (C H2SiMe2 N SiMe3)(NR2) 2](1; R= SiMe3), with
Ph3P CH2 affords the Th (IV) carbene [Th (CHPPh3)(NR2) 3](2) in good yield. In solution …

Abstract Treatment of [Ph3EMe][I] with [Na {N (SiMe3) 2}] affords the ylides [Ph3E= CH2](E=
As, 1As; P, 1P). For 1As this overcomes prior difficulties in the synthesis of this classical …
