The article was titled 《Synthesis and Structural Elucidation of Bisdibenzocorannulene in Multiple Redox States》.Reference of 3-Methoxyphenylboronic acid The article contains the following contents:
An anti-folded bowl-shaped bisdibenzocorannulene (BDBC) featuring a new chair-cyclohexane-like hexagon as a bridge of two dibenzocorannulene moieties was reported. The neutral compound showed multiple redox-active properties and could be converted to the corresponding redox states through chem. reduction or oxidation Chem. reduction of BDBC by stoichiometric addition of metallic potassium in the presence of [18]crown-6 ether, provided a radical anion BDBC.- and a dianion BDBC2-, resp.; while chem. oxidation by silver hexafluoroantimonate(V), converted the neutral compound to an open-shell singlet diradical dication (BDBC••)2+. The structural consequences of both electron-reduction and oxidation were closely related to the release of ring-strain of the bowl-shaped π-scaffold and imposed steric hindrance of the hexagonal bridge. In addition, the unusual open-shell nature of the dication could mainly be attributed to the changing of localized antiaromaticity in the closed-shell structure to delocalized character in the biradical, and thus the emergence of weakly bonded π-electrons.3-Methoxyphenylboronic acid(cas: 10365-98-7Reference of 3-Methoxyphenylboronic acid) was used in this study.
3-Methoxyphenylboronic acid(cas: 10365-98-7) belongs to boronic acids. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.Reference of 3-Methoxyphenylboronic acid
