Frustrated Lewis pair encounter complexes in an ionic liquid

Abstract: 'Frustrated Lewis Pairs' are believed to associate into an encounter complex held by dispersion forces, and that is it is this complex that interacts, and activates hydrogen, in a bi-molecular fashion. The formation of encounter complexes has been proposed by key theoretical evidence and computational studies, however experimental evidence to support their existence is very limited. In previous beam time, a direct experimental observation of the encounter complex between pairs of hindered Lewis acids and bases in a molecular solution was achieved. In this work, an ionic liquid solvent will be used to encourage the stability of the encounter complex, increasing its lifetime. In a molecular solvent, it is believed that 2 % of molecules exist as an encounter complex. greater proportion of encounter complexes would make their detection easier and modelling reveal more detail.
