A Novel Application of (Diacetoxyiodo)benzene for Carbon-Carbon Cleavage of Aryl Diamines and Synthesis of Quinones

[摘要]：A novel synthetic utility of hypervalent iodine reagent, (diacetoxyiodo)benzene for diamino aryl carbon-carbon cleavage is described. 1,2-Diamino aryl compounds were successfully converted into the corresponding nitriles, while the developed method was also useful for the preparation of quinones from corresponding 1,4-diamino aryl compounds. The advantages of this protocol are shorter reaction times and mild reaction conditions to obtain moderate to good yields.
