A new TBHP/TBAI-mediated reaction of propargyl alcohols with sulfonyl hydrazides in the presence of HOAc has been established, in which a wide variety of allenyl sulfones were obtained in moderate to excellent yields. Mechanistic studies indicate that thi

Nontoxic cyanide source: An unprecedented route to acrylonitriles by employing propargylic alcohols and para-tolylsulfonohydrazide as a combined cyano source has been developed (see scheme). This efficient and practical cyanation reaction proceeds through an FeCl3-catalyzed domino propargylic substitution/aza-Meyer-Schuster rearrangement sequence, the rearrangement process of which is reported for the first time.
