Asymmetric allylation of aryl aldehydes: studies on the scope and mechanism of the palladium catalyzed diethylzinc mediated umpolung using phosphoramidite ligands was written by Howell, Gareth P.;Minnaard, Adriaan J.;Feringa, Ben L.. And the article was included in Organic & Biomolecular Chemistry in 2006.Product Details of 185449-81-4 This article mentions the following:
Using modular, monodentate phosphoramidite ligands, enantioselective palladium catalyzed diethylzinc mediated allylation of aldehydes was achieved. The scope of the asym. C-C bond formation was investigated with respect to nucleophilic and electrophilic components and an alternative reaction mechanism is proposed based on our findings. In the experiment, the researchers used many compounds, for example, (S)-4-(Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl)morpholine (cas: 185449-81-4Product Details of 185449-81-4).
(S)-4-(Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl)morpholine (cas: 185449-81-4) belongs to chiral phosphine ligands. Thousands of arylphosphines have been used as chiral ligands for metal-catalyzed asymmetric reactions. Asymmetric catalytic performance is determined not only by the metal center but also by the chiral ligand selected.Product Details of 185449-81-4
