(+)-1,2-Bis2S,5S)-2,5-diphenylphospholano)ethane
(+)-1,2-Bis2S,5S)-2,5-diphenylphospholano)ethane S,S)-Ph-BPE) serves as a chiral phosphine ligand in the asymmetric hydrogenation of allylic sulfoxides, through a dynamic kinetic resolution process facilitated by Rh-catalyzed hydrogenation, utilizing insights from both theoretical and experimental mechanistic studies.
