Palladium‐Catalyzed Carbonylative Synthesis of Phthalimides from 1,2‐Dibromoarenes with Molybdenum Hexacarbonyl as Carbon Monoxide Source
AbstractWe 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. 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.magnified image
