Cationic BN-embedded polycyclic aromatic hydrocarbons (BN-PAH+s) were synthesized from a N-containing macrocycle via pyridine-directed tandem C-H borylation. Incorporating BN into PAH+ resulted in a remarkable hypsochromic shift due to an increase in the LUMO energy and the symmetry changes of the HOMO and LUMO. Electrophilic substitution or anion exchange of BN-PAH+ possessing tetrabromoborate as a counteranion (BN+[BBr4-]) afforded air-stable BN-PAH/PAH+s. Of these, BN+[TfO-] allowed reversible two-electron reduction and the formation of two-dimensional brickwork-type π-electronic ion pair with 1,2,3,4,5-pentacyanocyclopentadienyl anion, demonstrating the potential application of BN-PAH+ as electronic materials. In the experiment, the researchers used 2,6-Dibromopyridine(cas: 626-05-1HPLC of Formula: 626-05-1)
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.HPLC of Formula: 626-05-1
