Abstract:

A novel and efficient protocol towards (E)-β-vinyl sulfone derivatives by tetrabutylammonium Iodide(TBAI)/K2S2O8 mediated denitrative sulfonylation of readily prepared β-nitrostyrenes and economical sulfonylhydrazides was described. The corresponding (E)-β-vinyl sulfone compounds were obtained in moderate to good yields. Compared with reported methods, the present strategy features metal-free, acid and base-free.

Key words: (E)-vinyl sulfone;, β-nitrostyrenes;, sulfonylhydrazides, denitrative sulfonylation, radical reaction
