  2. Markovnikov's rule - Wikipedia

    en.wikipedia.org/wiki/Markovnikov's_rule

    Such reactions are said to be anti-Markovnikov, since the halogen adds to the less substituted carbon, the opposite of a Markovnikov reaction. The anti-Markovnikov rule can be illustrated using the addition of hydrogen bromide to isobutylene in the presence of benzoyl peroxide or hydrogen peroxide. The reaction of HBr with substituted alkenes ...

  3. Oxymercuration reaction - Wikipedia

    en.wikipedia.org/wiki/Oxymercuration_reaction

    The reaction follows Markovnikov's rule (the hydroxy group will always be added to the more substituted carbon). The oxymercuration part of the reaction involves anti addition of OH group but the demercuration part of the reaction involves free radical mechanism and is not stereospecific, i.e. H and OH may be syn or anti to each other.

  4. Morris S. Kharasch - Wikipedia

    en.wikipedia.org/wiki/Morris_S._Kharasch

    In 1869, a Russian chemist named Vladimir Markovnikov demonstrated that the addition of HBr to alkenes usually but not always resulted in a specific orientation. Markovnikov's rule, which stems from these observations, states that in the addition of HBr or another hydrogen halide to an alkene, the acidic proton will add to the less substituted carbon of the double bond.

  5. Hydroboration - Wikipedia

    en.wikipedia.org/wiki/Hydroboration

    In terms of regiochemistry, hydroboration is typically anti-Markovnikov, i.e. the hydrogen adds to the most substituted carbon of the double bond. That the regiochemistry is reverse of a typical HX addition reflects the polarity of the B δ+-H δ− bonds. Hydroboration proceeds via a four-membered transition state: the hydrogen and the boron ...

  8. Alexander Zaytsev (chemist) - Wikipedia

    en.wikipedia.org/wiki/Alexander_Zaytsev_(chemist)

    Zaytsev submitted his Dr. Chem. dissertation in 1870, and was awarded the degree over the indirect objections of Markovnikov (as second examiner of the dissertation, Markovnikov had written an overtly positive assessment that was meant to be read between the lines). The same year, he was promoted to Ordinary Professor of Chemistry.

  9. Hydrosilylation - Wikipedia

    en.wikipedia.org/wiki/Hydrosilylation

    Hydrosilylation of alkenes usually proceeds via anti-Markovnikov addition, i.e., silicon is placed at the terminal carbon when hydrosilylating a terminal alkene; [1] however, in the recent years, Markovnikov addition has become a growing field of research.
