KMnO4-mediated oxidative CN bond cleavage of tertiaryamines producing secondary amine was introduced, which was trapped by electrophiles (acyl chloride and sulfonyl chloride) to form amides and sulfonamides. The reaction could take place at mild condition, tolerating a wide range of function groups and affording products in moderate to excellent yields.

The development of catalysts for the amidation of tertiaryamines with acyl chlorides through oxidative C–N bond cleavage is rather challenging. By employing iodine as the catalyst, a broad range of aromatic acyl chlorides and tertiaryamines are efficiently converted into amides in good yields under mild conditions. A plausible mechanistic pathway is proposed for this transformation and is supported
