Abstract:
Divergent catalysis represents an exciting frontier for unlocking molecular structural diversity and exploring new activation modes. Here, we report the unexpected discovery of polarity-reversed divergent activation and functionalization of aliphatic aldehydes, where enolizable aliphatic aldehydes are selectively activated by nickel hydride to form two distinct alkylnickel intermediates divergently. This mild and operationally simple process enables the transformation of a wide variety of readily available aliphatic aldehydes, along with alkyl or aryl electrophiles, into the corresponding secondary alcohols or more challenging deoxygenated alkanes with excellent chemoselectivity.

02:17Reduction 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...
02:24Reduction 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.
02:47Alkynes 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.
