Abstract:
We describe a catalytic method for preparing allylic sulfones from unactivated alkenes with sodium sulfinates via a directed, copper(II)-catalyzed sulfonylation process. This transformation exhibits a broad scope, accommodating diverse 3-butenoic acids containing internal alkenes as well as aromatic and aliphatic sodium sulfinates. The reaction also features high regioselectivity and simple reaction conditions. Diverse transformations of allylic sulfone products are described. Control experiments were performed to elucidate the reaction mechanisms.

Preparation and Reactions of Sulfides
Radical Substitution: Allylic Bromination
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide
Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
