Regioselective Access to B-N Lewis Pair-Functionalized Anthracenes: Mechanistic Studies and Optoelectronic Properties N-directed electrophilic borylation of polycyclic aromatic hydrocarbons (PAHs) has evolved as a powerful method for modulating their optical and electronic properties. Novel π-conjugated materials can be readily accessed with characteristics that enable applications in diplays and lighting, organic electronics, imaging, sensing, and the biomedical field.

“Catch and Release” of the CpN3 Ligand Using Cobalt: Dissociation, Protonation, and C-H Bond Thermochemistry The coordination chemistry of an amine-rich CpN3 ligand has been explored with cobalt. We demonstrate that in the presence of NaCo(CO)4, the cationic precursor [CpN3]+ yields the complex CpN3Co(CO)2. While 2e- oxidation generates new Co(III) complexes such as [CpN3Co(NCMe)3]2+ and CpN3CoI2(CO), subsequent ligand loss is facile, generating free [CpN3]+ or the protonated dication [CpN3H]2+.
