(((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. Chiral phosphine catalysts: Nucleophilic phosphine catalysis often involves the formation of Lewis adducts, namely phosphonium (di)enolate zwitterions, as reaction intermediates.SDS of cas: 37002-48-5

Development of a Second Generation Palladium Catalyst System for the Aminocarbonylation of Aryl Halides with CO and Ammonia was written by Wu, Xiao-Feng;Neumann, Helfried;Beller, Matthias. And the article was included in Chemistry – An Asian Journal in 2010.SDS of cas: 37002-48-5 This article mentions the following:

An improved and general Pd(OAc)2/dppf-catalyzed aminocarbonylation of aryl and heteroaryl bromides and chlorides with CO and ammonia has been established. Primary amides are accessible under comparably mild conditions in good yield. 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: 37002-48-5SDS of cas: 37002-48-5).
