Abstract

Treatment of the Lewis acid B (C6F5) 3 with the Lewis base 2, 6-dimethylpiperidine (DMP) resulted in the formation of the classical Lewis acid· base adduct DMP-B (C6F5) 3, 1a, which was anticipated to undergo thermal dissociation to the “unquenched” Lewis centers. The free Lewis pair was able to form a frustrated Lewis pair (FLP), which induced heterolytic splitting of H2, affording the ionic product [DMPH][HB (C6F5) 3], 1b. FLPs, derived from B ( ...
