A facile and efficient I2O5 promoted iodosulfonylation of alkynes for direct synthesis of (E)-β-iodovinyl sulfones is described. This procedure affords various synthetically useful β-iodosulfonyl alkenes in moderate to good yields under peroxide free conditions.

Key words: I2O5, alkyne, sulfonylhydrazide, iodosulfonylation, (E)-β-iodovinyl
