Palladium-Catalyzed Double Carbonylation Reactions of o-Dihaloarenes with Amines in Phosphonium Salt Ionic Liquids
摘要:
Palladium-catalyzed double carbonylation of o-dihaloarenes with amines in phosphonium salt ionic liquids proceeds efficiently to give the corresponding N-substituted phthalimides. This process can tolerate a wide array of functional groups and affords products in excellent yields. The recyclability of the catalytic system was also investigated.
