《Highly Selective and Atom Economical Synthesis of 1,3-Enynes, Pyrroles and Furans by Manganese(I)-Catalyzed C-H Activation》 was published in ACS Catalysis in 2020. These research results belong to Cembellin, Sara; Dalton, Toryn; Pinkert, Tobias; Schaefers, Felix; Glorius, Frank. HPLC of Formula: 14516-54-2 The article mentions the following:
A highly selective Mn(I)-catalyzed alkenylation of arenes and heteroarenes with 1,3-diynes is described. The reported transformation overcomes regio-, chemo- and stereoselectivity challenges associated with the use of these coupling partners. Both sym. and unsym. diynes can be applied in this protocol, affording single isomers not only in the synthesis of 1,3-enynes I but also in the one-step preparation of pyrroles and furans. This simple and highly atom economical strategy features wide functional group tolerance, good reproducibility and preparative scale utility. The manganese catalyst plays a crucial role in this C-H activation protocol, enabling high selectivity with previously challenging internal alkynes. Furthermore, the synthetic value of the method is highlighted by diverse post-functionalizations of the final products. The experimental process involved the reaction of 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
