A metal-free method for intramolecular halocyclization of unfunctionalizedolefins was detailed. (Diacetoxyiodo)benzene (PIDA) was very effective for haloamidation, haloetherification, and halolactonization of unfunctionalizedolefins. In the presence of 1.1 equiv of PIDA and suitable halogen sources, a variety of unfunctionalizedolefins could be converted to the corresponding 1,2-bifunctional cyclic
