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.

A new reaction of 2-(phenylsulfonyl)-3-phenyloxaziridine (davis reagent): Oxidation of thiolates to sulfinates. Application to the synthesis of sulfones
(Matrix Presented) The first efficient and general method for the generation of sulfinate anions by oxidation of the corresponding thiolates is described. The oxidizing agent employed is the classical 2-(phenylsulfonyl)-3-phenyloxaziridine, commonly known as the Davis reagent. Subsequent S-alkylation of the sulfinates under phase-transfer catalysis affords sulfones 6 in 71-91% isolated yields (10 examples).

Cycloaddition of (Phenylsulfonyl)-1,2-propadienes with Diazomethane. Novel Rearrangement Reactions of the Resulting Cycloadducts
The cycloaddition reactions of several phenylsulfonyl-substituted allenes with diazomethane have been investigated.The major products formed were identified as 3-(phenylsulfonyl)-4-methylene-2-pyrazolines.These pyrazolines engage in a variety of mechanist
