摘要：

Reaction of aromatic compounds with bis(pyridine)iodonium(I) tetrafluoroborate (IPY2BF4) in the presence of HBF4 or CF3SO3H in CH2Cl2 at room temperature furnishes monoiodo derivatives with excellent regioselectivity and yields. Use of either acid gives comparable results with activated aromatics, whereas CF3SO3H is much more effective in the iodination of deactivated aromatics.
