The mild and efficient deuteration of terminal alkynes (mono-substituted alkynes) proceeded in the presence of a basic anion exchange resin, WA30, which is a polystyrene polymer bearing a tertiary amine residue on the aromatic nuclei, in heavy water (D2O) at room temperature. WA30 could be easily removed by a simple filtration and repeatedly reused.
Reduction of propargylic sulfones to (Z)-allylic sulfones using zinc and ammonium chloride

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.
