(((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) (cas: 37002-48-5) belongs to chiral phosphine ligands. Thousands of arylphosphines have been used as chiral ligands for metal-catalyzed asymmetric reactions. Trivalent phosphorus compounds called phosphines have a tetrahedral electron-group geometry which makes them structurally analogous to amines.Category: chiral-phosphine-ligands

Novel 1,4-diphosphanes with imidazolidin-2-one backbones as chiral ligands: highly enantioselective Rh-catalyzed hydrogenation of enamides was written by Lee, Sang-Gi;Zhang, Yong Jian;Song, Choong Eui;Lee, Jae Kyun;Choi, Jung Hoon. And the article was included in Angewandte Chemie, International Edition in 2002.Category: chiral-phosphine-ligands This article mentions the following:

Asym. hydrogenation of N-acetyl α-aryl enamides ArC(:CHR1)NHAc [Ar = (un)substituted Ph; R1 = H, Me, Et] was catalyzed by [Rh(cod)2]BF4 and 1,4-diphosphane ligands I (R = H, Me, Et, etc.). I were prepared from a L-tartaric acid derivative In the experiment, the researchers used many compounds, for example, (((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) (cas: 37002-48-5Category: chiral-phosphine-ligands).
