Planar Polycyclic Oxaphosphoranes Incorporating a Benzophosphole Unit
Zheng Duan, Xu Zhao, François Mathey, Zhenjie Gan, Chaopeng Hu
A facile method to synthesize quaternized benzophospholes on gram scale was reported, and the products were isolated by simple filtration. During this research, a series of σ5-oxaphosphoranes incorporating polycyclic aromatic hydrocarbons (PAHs) were obtained. The grafting of α-phenolate groups on the phosphorus center enhances the coplanarity of the system.
