Tandem Phospha-Friedel−Crafts Reaction toward Curved π-Conjugated Frameworks with a Phosphorus Ring Junction
摘要:
The tandem phospha-Friedel Crafts reaction transforms dichloro(m-teraryl)phosphine to the corresponding triarylphosphine derivatives containing curved pi-conjugated frameworks with a phosphorus ring junction. The rigid molecular frameworks enable these unprecedented phosphine compounds to hold an extended pi-conjugation spread over the whole molecule.

Tandem intramolecular electrophilic arene borylation was developed to facilitate access to B-doped polycyclic aromatic hydrocarbons (PAHs). DFT calculations revealed that electrophilic arene borylation occurred via a four-membered ring transition state, in which C–B and H–Br bonds formed in a concerted manner. An organic light-emitting diode employing the B-doped PAH as an emitter and a B-doped PAH-based
