Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 131457-46-0, Name is (4S,4S)-2,2-(Propane-2,2-diyl)bis(4-phenyl-4,5-dihydrooxazole), molecular formula is , belongs to catalyst-ligand compound.

Rh-catalyzed asymmetric hydrogenation of alpha-aryl-beta-alkylvinyl esters with chiral ferrocenylphosphine-phosphoramidite ligand
An enantioselective Rh-catalyzed hydrogenation of E/Z mixtures of trisubstituted vinyl esters has been disclosed. With a combination of [Rh(COD)(2)]BF4 and a structurally fine-tuning chiral ferrocenylphosphine-phosphoramidite ligand as the catalyst, a variety of E/Z mixtures of alpha-aryl-beta-alkylvinyl esters have been successfully hydrogenated in high yields and with good to high enantioselectivities (up to 96% ee). The presence of a small amount of (BuOH)-Bu-t proved to be beneficial to improve the hydrogenation outcome. (C) 2021 Elsevier Ltd. All rights reserved.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 131457-46-0, in my other articles.
