Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C3H5NO2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 497-25-6
We demonstrate here, a new polystyrene supported Cu(ii) catalyzed proficient synthetic methodology for the facile N-arylation of aromatic, aliphatic, cyclic and heterocyclic amides with aryl halides under neat conditions. The catalyst, PS-Cu(ii)-ala, was prepared through the grafting of copper metal on a polystyrene-beta-alanine imine network. The catalyst shows a wide range of substrate scope and excellent functional group tolerance, and produces the desired anilides in mostly high yields. The material is thoroughly characterized by DRS-UV, FT-IR, AAS, FE-SEM, TGA analysis and energy dispersive X-ray (EDX) studies. The catalyst can be easily recovered from the reaction medium and reused without significant loss of its catalytic activity suggesting future potential of this catalyst.
