I2/TBHP-mediated reaction of sulfonylhydrazides with alkynes: synthesis of (E)-β-iodovinyl sulfones

An efficient and simple procedure for the syntheses of (E)-β-iodovinyl sulfones through TBHP mediated reaction of sulfonylhydrazides and iodine with aryl acetylenes has been developed. This method offers several advantages such as high atom economy, environmentally benign oxidant, less byproduct, and easy operation.
