Abstract

Oxidative halogenation with trityl chloride provides convenient access to CeIV and UIV chloroamides [M(N{SiMe3}2)3Cl] and their N-heterocyclic carbene derivatives, [M(L)(N-{SiMe3}2)2Cl] (L= OCMe2CH2(CNCH2CH2NDipp) Dipp=2,6-iPr2C6H3). Computational analysis of the bonding in these and a fluoro analogue, [U(L)(N{SiMe3}2)2F], provides new information on the covalency in this relative rare oxidation state for molecular cerium complexes. Computational studies reveal increased Mayer bond orders in the actinide carbene bond compared with the lanthanide carbene bond, and natural and atoms-in-molecules analyses suggest greater overall ionicity in the cerium complexes than in the uranium analogues.

Abstract

A new and modular route to bidentate ligands that combines an alkoxide with a saturated backbone N-heterocyclic carbene (NHC) is presented. The bi(heterocyclic) compounds are formally the addition product of a saturated NHC and the alcohol group of the N-functionalised arm. Using these compounds, the synthesis and structural characterisation of the first electropositive metal complexes of saturated N-heterocyclic carbenes has been achieved, and examples structurally characterised for the yttrium(III) and the uranyl [UO(2)](2+) cations.
