Abstract
Esters and thioesters are of great interest to chemists from a biological and medicinal point of view, that's why the synthesis of these compounds is always a popular research field in organic chemistry. In this method, we first synthesized Fe3O4@BA/Pyrim-Carboxamide-NiCl2 nanocatalyst, then studied its catalytic application in the preparation of esters and thioesters through carbonylation and thiocarbonylation of aryl iodides. The results of these experiments showed that the Fe3O4@BA/Pyrim-Carboxamide-NiCl2 catalyst in the presence of KOAc in ChCl-Urea solvent can easily conducted a wide range of reactions and the desired ester and thioester products were synthesized with very good yields. The structure of the Fe3O4@BA/Pyrim-Carboxamide-NiCl2 catalyst before use and after recovery was well confirmed by a series of techniques. Among the features of this method, the following can be mentioned: the synthesis of esters and thioesters with very good yields, using mild conditions, simple separation of the catalyst, high reusability of the catalyst, providing NMR analysis for all the obtained products.
