The synthesis of Frustrated Lewis Pairs (FLP¿s) have recently experienced a huge surge in popularity as they have been found to be a novel approach for the activation of small molecules. One of the most important applications of FLP¿s is the discovery of the low temperature heterolytic splitting of H2. Furthermore, very recently we used this reaction to develop the first report of the homogeneous reduction of CO2 to methanol.1 We have subsequently been studying the mechanism of CO2 reduction and in particular the kinetics and thermodynamics of the heterolytic cleavage of H2 using three novel Frustrated Lewis Pair systems in order to develop more active systems. To this end, we propose an 8 day data collection to accurately determine the hydrogen positions in the FLP system, HB(C6CF5)2(C6Cl5)]¿[HDABCO]+.
