  2. Hydroacylation - Wikipedia

    en.wikipedia.org/wiki/Hydroacylation

    Hydroacylation is a type of organic reaction in which an electron-rich [1] unsaturated hydrocarbon inserts into a formyl C-H bond. With alkenes, the product is a ketone: RCHO + CH 2 =CHR' → RC(O)CH 2 CH 2 R' With an alkyne instead, the reaction produces an α,β-unsaturated ketone. [2] The reaction requires a metal catalyst or a radical ...

  3. Addition reaction - Wikipedia

    en.wikipedia.org/wiki/Addition_reaction

    Top to bottom: electrophilic addition to alkene, nucleophilic addition of nucleophile to carbonyl and free-radical addition of halide to alkene. Depending on the product structure, it could promptly react further to eject a leaving group to give the addition–elimination reaction sequence. Addition reactions are useful in analytic chemistry ...

  4. Woodward cis-hydroxylation - Wikipedia

    en.wikipedia.org/wiki/Woodward_cis-hydroxylation

    The Woodward cis-hydroxylation (also known as the Woodward reaction) is the chemical reaction of alkenes with iodine and silver acetate in wet acetic acid to form cis-diols. [1] [2] (conversion of olefin into cis-diol) The reaction is named after its discoverer, Robert Burns Woodward. The Woodward cis-hydroxylation

  5. Syn and anti addition - Wikipedia

    en.wikipedia.org/wiki/Syn_and_anti_addition

    In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.

  6. Hydrocyanation - Wikipedia

    en.wikipedia.org/wiki/Hydrocyanation

    Usually the substrate is an alkene and the product is a nitrile. The reaction proceeds via the oxidative addition of HCN to a low-valent metal complex to give a hydrido cyanide complex. Subsequent binding of the alkene gives the intermediate M(H)(CN)L n (alkene), which then undergoes migratory insertion to give an alkylmetal

  7. Reaction intermediate - Wikipedia

    en.wikipedia.org/wiki/Reaction_intermediate

    Carbocations are formed in two major alkene addition reactions. In an HX addition reaction, the pi bond of an alkene acts as a nucleophile and bonds with the proton of an HX molecule, where the X is a halogen atom. This forms a carbocation intermediate, and the X then bonds to the positive carbon that is available, as in the following two-step ...

  8. Hydroamination - Wikipedia

    en.wikipedia.org/wiki/Hydroamination

    The addition of hydrogen and an amino group (NR 2) using reagents other than the amine HNR 2 is known as a "formal hydroamination" reaction. Although the advantages of atom economy and/or ready available of the nitrogen source are diminished as a result, the greater thermodynamic driving force, as well as ability to tune the aminating reagent ...

  9. Sharpless asymmetric dihydroxylation - Wikipedia

    en.wikipedia.org/wiki/Sharpless_asymmetric_di...

    The reaction has been applied to alkenes of virtually every substitution, often high enantioselectivities are realized, with the chiral outcome controlled by the choice of dihydroquinidine (DHQD) vs dihydroquinine (DHQ) as the ligand. Asymmetric dihydroxylation reactions are also highly site selective, providing products derived from reaction ...
