The article was titled 《Manganese catalyzed enantio- and regioselective hydrogenation of α,β-unsaturated ketones using an imidazole-based chiral PNN tridentate ligand》.HPLC of Formula: 14516-54-2 The article contains the following contents:
The enantioselective 1,2-reduction of α,β-unsaturated ketones has been achieved using a chiral pincer Mn catalyst. A series of PNN tridentate ligands containing benzimidazole groups were designed with ferrocene as the backbone, which coordinated with Mn to form the active catalyst. This mild process represents a general method to access chiral allyl alcs. with high catalytic activity (up to 9500 TON) and high enantioselectivity (66-86% ee). Furthermore, this catalytic system provides a novel synthesis of key pharmaceutical intermediates of cannabidiol. In the experiment, the researchers used Bromopentacarbonylmanganese(I)(cas: 14516-54-2HPLC of Formula: 14516-54-2)
Bromopentacarbonylmanganese(I)(cas: 14516-54-2) has many other uses. It is used in the formation of (eta6-arene)tricarbonylmanganese(I) by reacting with arene (arene= hexamethyl benzene, 1,2,4,5-tetramethyl benzene, mesitylene, p-xylene and toluene) in the presence silver salt.HPLC of Formula: 14516-54-2
