摘要：
The present invention relates to a process for the preparation of iodinated anilines; in particular, it relates to a process including the direct iodination of 3,5-disubstituted anilines to the corresponding 3,5-disubstituted-2,4,6-triiodoanilines, which are useful intermediates for the synthesis of x-ray contrast media, and to the preparation of the contrast media themselves.
