Tetrabutylammonium iodide catalyzed allylic sulfonylation of Baylis-Hillman acetates with sulfonylhydrazides in water

A tetrabutylammonium iodide catalyzed method for the synthesis of allyl aryl sulfone derivatives with Baylis-Hillman acetates and sulfonylhydrazides using tert-butyl hydroperoxide as an oxidation agent in water has been developed. In this process, the group eliminated from the sulfonyl precursor is molecular nitrogen.
