An efficient and facile method for the iodo-functionalization of alkenes 5 and alkynes 6 by using recyclable ni-iodosylbenzoic acid (2) was developed. The final products can be easily isolated without any chromatographic purification by simple treatment of the crude mixture with an anionic exchange resin. Unreacted m-iodosylbenzoic acid and reduced m-iodobenzoic acid are effectively recovered from the resin by acidification with hydrochloric acid. (c) 2008 Elsevier Ltd. All rights reserved.
