We describe here a convenient and mild, carbon monoxide gas-free palladium-catalyzed procedure to obtain N-substituted phthalimides with molybdenum hexacarbonyl as carbon monoxide precursor. E.g., in presence of molybdenum hexacarbonyl, Pd(OAc)2, CataCXium A, and DBU in toluene at 100 °C, reaction of 1,2-Br2C6H4 and BuNH2 gave 84% phthalimide derivative I. These conditions tolerate a number of functional groups on the benzene ring as well as a number of amines and give the corresponding phthalimides in good to excellent yields. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Category: benzothiophene).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, sertaconazole, and also BTCP.Category: benzothiophene
