摘要：

The first heterogeneous carbonylative annulation of 2-aminobenzamides with aryl iodides was achieved in N, N-dimethylformamide (DMF) at 120 degrees C under 10 bar of carbon monoxide by using an MCM-41-immobilized bidentate phosphine palladium(II) complex [MCM-41-2P-Pd(OAc)(2)] as catalyst and 1,8-diazabicycloundec-7-ene (DBU) as base, yielding a wide variety of quinazolinone derivatives in good to excellent yields. The new heterogeneous palladium catalyst can easily be prepared by a simple procedure from commercially readily available reagents, and recovered by filtration of the reaction solution, and recycled up to eight times without significant loss of activity.
