The clean isomerization of 1,2‐allenyl sulfoxides in the presence of NaSO 2 Ph afforded 2‐alkynylic phenyl sulfoxides in good yields and selectivities. Although strong base‐catalyzed isomerization of allenes to alkynes is known, the mechanism for the current reaction is interesting for the obvious reason that NaSO 2 Ph is a weak base.
