Abstract

Considerable progress has been made over the last decades towards the stabilisation of very low oxidation state s- and p-block compounds. These systems are often very reactive and are finding a variety of applications, the most topical of which is the "transition metal-like" activation of small molecules. Very bulky chelating ligands are normally required to kinetically protect such compounds from decomposing via disproportionation, and other, pathways. Surprisingly little work has been carried out in recent years dealing with monodentate amido complexes of s- and p-block metals in low oxidation states. In this lecture the development of a new class of extremely bulky amido ligands will be discussed, as will their use in the preparation of previously inaccessible, coordinatively unsaturated low oxidation state s-, p- and first row d-block complex types, e.g. 1-4. The extremely facile "transition metal-like" reactivity of these compounds towards small molecule (e.g. H2, CO2, NH3 etc.) activations will also be detailed. The ultimate aim of this work is the development of s- and p-block metal complexes that can act as effective catalysts in processes normally requiring expensive (and often toxic) late transition metal catalysts to proceed.
