Oly (4-vinylpyridine)‎ ICl : an efficient system for the regioselective iodination of activated aromatic compounds

Abstract EN

Poly(4-vinylpyridine)/ICl is reported as an efficient system for the regioselective iodination of activated aromatic compounds.

Various activated aromatic compounds were iodinated into the corresponding aryl iodides in high yields.

Poly(4-vinylpyridine) can be recovered by simple filtration and recycled up to 6 consecutive runs without significant decrease in its catalytic activity.

This method provides many advantages such as good selectivity between ortho and para positions of aromatic compounds, simple work-up, mild conditions and high product yields.
