《Development of a practical non-noble metal catalyst for hydrogenation of N-heteroarenes》 was written by Papa, Veronica; Cao, Yixuan; Spannenberg, Anke; Junge, Kathrin; Beller, Matthias. Category: bromides-buliding-blocks And the article was included in Nature Catalysis in 2020. The article conveys some information:
The chemoselective reduction of quinolines and related N-heterocycles by mol. hydrogen, using a simple Mn(I) complex [Mn(CO)5Br] was reported. Under very mild reaction conditions this catalytic system was able to reduce a wide range of quinolines, affording high yields of the corresponding tetrahydroquinolines, a scaffold present in many bioactive compounds, including marketed pharmaceuticals. Mechanistic studies revealed the formation of the active catalyst and also show the important role of a concomitantly formed Mn(II) species and HBr for the hydrogenation of the heterocyclic substrates. The results came from multiple reactions, including the reaction of Bromopentacarbonylmanganese(I)(cas: 14516-54-2Category: bromides-buliding-blocks)
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.Category: bromides-buliding-blocks
