Product Details of 3411-48-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Multicomponent Reaction of Phosphines, Benzynes, and CO2: Facile Synthesis of Stable Zwitterionic Phosphonium Inner Salts. Author is Xie, Pei; Yang, Shoushan; Guo, Yuyu; Cai, Zhihua; Dai, Bin; He, Lin.
The first synthesis of benzyne-derived stable zwitterions is reported. Benzynes generated in situ from 2-(trimethylsilyl)aryl triflates undergo a multicomponent reaction with phosphines and CO2 to produce the stable 1,5-zwitterionic species in moderate to excellent isolated yields, which provides a novel method for the preparation of phosphonium inner salts, e.g. I, under mild and transition-metal-free conditions.
In some applications, this compound(3411-48-1)Product Details of 3411-48-1 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
