Abstract
1. Depending on the reaction conditions, the iodination of 5-hydroxypicolinic acid proceeds with the formation of the 6-iodo derivative, or 2,6-diiodo- and 2,4,6-triiodo-3-hydroxypyridine. 2. The iodination of 3-hydroxyisonicotinic acid leads to the formation of either the 2-iodo derivative or 2,4,6-triiodo-3-hydroxypyridine.
