<dc:description>A tandem 1,3-sulfur migration followed&#xd;
by iodocyclization reaction of propargylic sulfides&#xd;
in the presence of NIS in HFIP has been developed&#xd;
to synthesize indene-based β-iodoalkenyl sulfides.&#xd;
The choice of the reaction media is crucial to&#xd;
promote the reaction. The proposed mechanism&#xd;
involving the initial NIS activation by HFIP and&#xd;
favoring the sulfur migration of the starting propargylic thioether via cationic intermediates is experimentally supported. In addition, the suitability of&#xd;
selected indene-based β-iodoalkenyl sulfides as&#xd;
building blocks for subsequent C C bond-forming&#xd;
reactions has been demonstrated.</dc:description>
