Facile Reversibility by Design: Tuning Small Molecule Capture and Activation by Single Component Frustrated Lewis Pairs
A series of single component FLPs
has been investigated for small
molecule capture, with the finding that through tuning of both the
thermodynamics of binding/activation and the degree of preorganization
(i.e., Δ<i>S</i><sup>⧧</sup>) reversibility
can be brought about at (or close to) room temperature. Thus, the
dimethylxanthene system {(C<sub>6</sub>H<sub>4</sub>)<sub>2</sub>(O)CMe<sub>2</sub>}(PMes<sub>2</sub>)(B(C<sub>6</sub>F<sub>5</sub>)<sub>2</sub>): (i) heterolytically cleaves dihydrogen to give an equilibrium
mixture of FLP and H<sub>2</sub> activation product in solution at
room temperature and (ii) reversibly captures nitrous oxide (uptake
at room temperature, 1 atm; release at 323 K)
