    Hydroboration-Oxidation of Alkenes03:08

    Hydroboration-Oxidation of Alkenes

    In addition to the oxymercuration–demercuration method, which converts the alkenes to alcohols with Markovnikov orientation, a complementary hydroboration-oxidation method yields the anti-Markovnikov product. The hydroboration reaction, discovered in 1959 by H.C. Brown, involves the addition of a B–H bond of borane to an alkene giving an organoborane intermediate. The oxidation of this intermediate with basic hydrogen peroxide forms an alcohol.
    Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide02:44

    Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

    Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.
    Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate02:21

    Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate

    Alkenes can be dihydroxylated using potassium permanganate. The method encompasses the reaction of an alkene with a cold, dilute solution of potassium permanganate under basic conditions to form a cis-diol along with a brown precipitate of manganese dioxide.
    Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids02:04

    Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids

    Diols are compounds with two hydroxyl groups. In addition to syn dihydroxylation, diols can also be synthesized through the process of anti dihydroxylation. The process involves treating an alkene with a peroxycarboxylic acid to form an epoxide. Epoxides are highly strained three-membered rings with oxygen and two carbons occupying the corners of an equilateral triangle. This step is followed by ring-opening of the epoxide in the presence of an aqueous acid to give a trans diol.

    Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation

    Introduction
    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 Hydrogenation02:24

    Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

    Introduction
    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.
