A novel and efficient protocol for the synthesis of β-keto-sulfone derivatives via TBAI/TBHP mediated oxidative cross-coupling of vinyl acetates with sulfonylhydrazides has been developed.
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.
