At the same time, compared with the Por-COF (P12 + L19), which is connected with C=N, the C=C bond in Por-sp2c-COF would not be destroyed by benzylamine, which guarantees its stability under the reaction conditions. In addition, Por-sp2c-COF can be used to catalyze the selective ...
The non-covalent intermolecular bond in the B···BeR2 complexes is shown to result from the interaction of the electrophilic band around the Be atom of BeR2 (as indicated by the molecular electrostatic potential surface) with non-bonding electron pairs of the base, B, and may be described...
