We recently embarked on a program of research to investigate the structure, bonding, and reactivity of complexes that contain uranium–metal bonds;(27-34) this was stimulated by their paucity in the literature compared to the well-developed area of metal–metal bonding in the d-block.(6, 7) We have found the Tren TMS ligand to be an excellent ancillary ligand for complexes containing uranium–metal bonds, as demonstrated by our use of the complexes [U(Tren TMS ...
