Abstract

This chapter covers the synthesis, structure and bonding, and reactivity of actinide complexes of buta-, and penta-dienyl ligands. First, the small number of homoleptic, and non-cyclopentadienyl heteroleptic hydrocarbyl actinide complexes are presented in brief. This is followed by an overview of the synthesis and reactivity of heteroleptic hydrocarbyl actinide complexes in a tris-cyclopentadienyl and bis-permethylcyclopentadienyl ancillary ligand environment. The bulk of this chapter then provides comprehensive coverage of actinide complexes with composite four-carbon ligands. First, actinide complexes containing acyclic 2-butene-1,4-diyl and 1,3-butadiene-1,4-diyl ligands. Second, the planar five-membered metallacyclic complexes, actinacyclopentadienes, actinacyclopentatrienes, and an actinacyclopentyne. The actinacyclic complexes display significant differences in bonding and reactivity depending on the level of ligand unsaturation. Third, recent developments in complexes of the cyclobutadienyl dianion are reported. Finally, a conclusion provides a summary and an outlook on future work.
