(Pyridin-2-ylmethyl)triel Derivatives as Masked Frustrated Lewis Pairs. Interactions and CO2-Sequestration
The isolated (pyridin-2-ylmethyl)triel derivatives (triel=B, Al and Ga) show an intramolecular N⋅⋅⋅Tr triel bond. Their reaction with CO2 indicate that they can be classified as masked frustrated Lewis pairs (mFLP). The adduct formation proceeds in two steps: breaking the intramolecular N⋅⋅⋅Tr bond and adduct formation with Tr−O and N−C covalent bonds, being final products always more stable.
