GR/T09613/01 Arsine Macrocycles | University of Southampton

Project overview

The project involves the synthesis of a selected range of macrocyclic ligands based upon arsenic, which will be strongly coordinating to many p-block metal/metalloid acceptors and which will present very different steric and electronic properties to acyclic arsines. Only a limited number of such ligands are presently known, and the development/refinement of good routes to their synthesis will permit their use in transition metal, organometallic and catalysis systems in the future.In this project these ligands will be complexed with selected p-block metals/metalloids and the resulting complexes will be fully characterised analytically, spectroscopically and structurally. No compounds of the type proposed are known and this is a challenging project, but with the necessary likelihood of success appropriate for a PhD studentship. It is anticipated that the structures and properties of the new complexes will be very different to the few examples with acyclic arsine ligands currently known. The results will contribute to the systematic understanding of such topics as the stereochemical activity (or otherwise) of the p-block element based lone pair, the occurrence and extent of secondary bonding interactions, and how these factors influence structural and reaction chemistry in this area.
