Preparation of Propargylic Sulfinates and their [2,3]-Sigmatropic Rearrangement to Allenic Sulfones

The scope of the [2,3]-sigmatropic rearrangement of propargylic sulfinates to allenic sulfones by silver catalysis was expanded. A series of new propargylic sulfinate esters was generated from a variety of aromatic and heteroaromatic sulfonyl chlorides an

Synthesis of thiophenes from allenyl sulfones involving α,β-unsaturated sulfines as intermediates

The synthesis of thiophenes starting from allenyl sulfones, via intermediate formation of α,β-unsaturated sulfines, is described.The allenyl sulfones were synthesized by a -sigmatropic rearrangement of appropriately substituted prop-2-ynyl sulfinates
