摘要

Iodoarenes are valuable, versatile synthetic intermediates and have found wide applications in medicine and biochemistry. 1 However, the electrophilic nature of iodine is weaker than bromine and chlorine. For this and other reasons, there are only a limited number of methods for direct iodination of deactivated aromatics. Some arenes with electron-withdrawing substituents can be iodinated by I 2 /HNO 3 /H 2 SO 4 /AcOH, 2 I 2 /Ag 2 SO 4 /H 2 SO 4 , 3 I 2 /oleum, 4 I 2 ...
