Reduction of Propargylic Sulfones to (Z)-Allylic Sulfones using Zinc and Ammonium Chloride.

Description

No / Propargylic sulfones can be cis-hydrogenated using commercial zinc powder and ammonium chloride in THF¿water at room temperature, the major products being the corresponding (Z)-allylic sulfones. Other reducible groups (alkene, benzyloxy) are not affected. Allenylsulfones are implicated in one of the possible reaction pathways.
