Iodine-containing 4,7-dihalobenzo[b]thiophene building blocks and related iodobenzo[b]thiophenes: Promising molecular scaffolds for bio-inspired molecular architecture

This review describes preparations and reactions of 4,7-dihalobenzo[b]thiophenes bearing iodine atom(s). A short survey of typical preparative methods for iodobenzo[b]thiophenes and relatively simple benzo[b]thiophenes is included. Reactions of the iodine-containing 4,7-dihalobenzo[b]thiophenes are shown and their application to α helix-inspired artificial molecular architecture is referred.
