(β-Organochalcogenyl)allylphenyl sulfoxides 2 were prepared by treatment of allenyl sulfoxides 1 with sodium organyl chalcogenolates in good yields. The reaction was regioselective, giving exclusively one isomer in all cases. The applications of (β-phenyltelluro)allylphenyl sulfoxide 2d and (β-organosulfanyl)allylphenyl sulfoxide 2m in organic synthesis were also described.

Iodohydroxylation reaction of allenyl phenyl sulfoxides with I-2 can smoothly proceed to generate (E)-2-iodo-3-hydroxy-1-alkenyl sulfoxides with excellent regio- and stereoselectivity in high or excellent yields. The configuration of E-2a was determined by the X-ray diffraction study.
