Easy Access To Allylic Sulfones Through Transition Metal-Free Hydrosulfonylation Of Allenes
Keyword(s):
A Brønsted acid-mediated addition of (hetero)aryl and (cyclo)alkyl sodium sulfinates to <i>N</i>-allenyl derivatives is described under very smooth conditions. This reaction provided a practical and efficient protocol for the synthesis of allylic sulfones in an atom- and step-economic fashion. In addition, an one-step double hydrosulfonylation has also been demonstrated, affording the corresponding 1,3-disulfone in to good yield.<br>
