(R)-(6,6′-Dimethoxybiphenyl-2,2′-diyl)bis[bis(3,4,5-trimethoxyphenyl)phosphine](cas: 256390-47-3) belongs to chiral phosphine ligands. Nucleophilic phosphine catalysis often involves the formation of Lewis adducts, namely phosphonium (di)enolate zwitterions, as reaction intermediates. Electric Literature of C50H56O14P2 These intermediates are formed through nucleophilic attack of the phosphine catalysts at electron-poor nuclei (normally carbon atoms) and then proceed through several steps to form new chemical bonds.

In 2009,Chemistry – A European Journal included an article by Hashmi, A. Stephen K.; Hamzic, Melissa; Rominger, Frank; Bats, Jan W.. Electric Literature of C50H56O14P2. The article was titled 《Gold Catalysis: Enantiotopos Selection》. The information in the text is summarized as follows:

The Au-catalyzed enantioselective cycloisomerization of furyldialkynes, e.g. I, for the preparation of phenols, e.g. II, was reported. After reading the article, we found that the author used (R)-(6,6′-Dimethoxybiphenyl-2,2′-diyl)bis[bis(3,4,5-trimethoxyphenyl)phosphine](cas: 256390-47-3Electric Literature of C50H56O14P2)
