Claim:
1. A process for the preparation of organic iodide comprising the steps of: (a) reacting an amide with iodine and [bis(acyloxy)iodo]arene in aprotic solvent to yield N-iodoamide and iodoarene as co-product; (b) reacting an organic compound with said N-iodoamide of step (a) to yield desired organic iodide and amide as co-product; and (c) recovering said amide co-product from the reaction mixture of step (b); wherein said amide is 4,4-dimethyloxazolidin-2-one, saccharin or 3,5,5-trimethylhydantoin and said N-iodoamide is 3-iodo-4,4-dimethyloxazolidin-2-one (IDMO), N-iodosaccharin (NISac) or 1-iodo-3,5,5-trimethylhydantoin (1-ITMH), respectively.
