In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A General and Highly Selective Cobalt-Catalyzed Hydrogenation of N-Heteroarenes under Mild Reaction Conditions, published in 2017, which mentions a compound: 2343-22-8, Name is 5-Fluoroindoline, Molecular C8H8FN, Recommanded Product: 2343-22-8.
Herein, a general and efficient method for the homogeneous cobalt-catalyzed hydrogenation of N-heterocycles, under mild reaction conditions, is reported. Key to success is the use of the tetradentate ligand tris(2-(diphenylphosphino)phenyl)phosphine. This non-noble metal catalyst system allows the selective hydrogenation of heteroarenes in the presence of a broad range of other sensitive reducible groups.
After consulting a lot of data, we found that this compound(2343-22-8)Recommanded Product: 2343-22-8 can be used in many types of reactions. And in most cases, this compound has more advantages.
