Alkylation of potassium selenosulfate with allylic halides gives Se-allyl seleno Bunte salts. On reaction with thiols at room temperature, these afford mixed dialkyl selenosulfides, which undergo 2,3-sigmatropic rearrangement with loss of selenium, either spontaneously or with assistance by triphenylphosphine, thereby
