The first example of the direct halosulfenylation of benzo[b]furans with commercially available disulfides and N-halosuccinimides has been achieved, providing an efficient metal-free synthetic pathway to access diverse 3-halo-2-thiobenzo[b]furans in moderate to excellent yields. In particular, a halogen (e.g., bromo or iodo) substituent on the benzo[b]furan ring is amenable for further synthetic elaborations thereby broadening the diversity of the products.

The use of TMPMgCl·LiCl and iPrMgCl·LiCl allows a sequential 2,3-difunctionalization of various 2-arylsulfinyl furans, thiophenes and benzofurans. Subsequent use of the same reagents permits a selective full functionalization of all 4 positions of the fur
