| Abstract: | Synthesis and facile rearrangement and cyclization reaction of new dipropargylic disulfides are described. A possible mechanism for these transformations involving an initial double [2,3]-sigmatropic rearrangement to the elusive diallenyl disulfides via a thiosulfoxide intermediates is suggested. |
