Abstract:
Diacyl peroxides serve as dual-function oxidants and acyloxy sources in a Pd-catalyzed oxidative borylation-acyloxylation of enallenes. Under mild conditions, this protocol delivers stereodefined vinylboronate esters with high chemo- and stereoselectivity across 80+ examples of enallenes and diacyl peroxides. The method avoids external metal or quinone oxidants and is applicable to gram-scale synthesis, product derivatization, and recyclable heterogeneous Pd catalysis. DFT calculations support accessible oxypalladation pathways that converge before C-B bond-forming reductive elimination.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.

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.
