Meng, Lingpu; Yang, Jingjie; Duan, Mei; Wang, You; Zhu, Shaolin published an article in 2021. The article was titled 《Facile Synthesis of Chiral Arylamines, Alkylamines and Amides by Enantioselective NiH-Catalyzed Hydroamination》, and you may find the article in Angewandte Chemie, International Edition.Formula: C20H20BrP The information in the text is summarized as follows:
Regio- and enantioselective hydroarylamination, hydroalkylamination and hydroamidation of styrenes was developed by NiH catalysis with a simple bioxazoline ligand under mild conditions. A wide range of enantioenriched benzylic arylamines, alkylamines and amides was easily accessed by nitroarenes, hydroxylamines and dioxazolones, resp. as amination reagents. The chiral induction in these reactions was proposed to proceed through an enantiodifferentiating syn-hydronickellation step. In the experimental materials used by the author, we found Ethyltriphenylphosphonium bromide(cas: 1530-32-1Formula: C20H20BrP)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Formula: C20H20BrP
