  2. 2-Pentyne - Wikipedia

    en.wikipedia.org/wiki/2-Pentyne

    Ethylmethylacetylene, 1-Ethyl-2-methylacetylene propyl acetylene. ... 2-Pentyne, an organic compound with the formula CH 3 CH 2 C≡CCH 3 and is an internal alkyne.

  3. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    Because the cis–trans and E–Z systems compare different groups on the alkene, it is not strictly true that Z corresponds to cis and E corresponds to trans. For example, trans-2-chlorobut-2-ene (the two methyl groups, C1 and C4, on the but-2-ene backbone are trans to each other) is (Z)-2-chlorobut-2-ene (the chlorine and C4 are together ...

  4. Transition metal alkyne complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_alkyne...

    Acrylic acid was once prepared by the hydrocarboxylation of acetylene: [11] C 2 H 2 + H 2 O + CO → H 2 C=CHCO 2 H. With the shift away from coal-based (acetylene) to petroleum-based feedstocks (olefins), catalytic reactions with alkynes are not widely practiced industrially. Polyacetylene has been produced using metal catalysis involving ...

  5. Oxymercuration reaction - Wikipedia

    en.wikipedia.org/wiki/Oxymercuration_reaction

    In organic chemistry, the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene (R 2 C=CR 2) into a neutral alcohol. In oxymercuration, the alkene reacts with mercuric acetate (AcO−Hg−OAc) in aqueous solution to yield the addition of an acetoxymercury (−HgOAc) group and a hydroxy (−OH) group across the ...

  6. Transmetalation - Wikipedia

    en.wikipedia.org/wiki/Transmetalation

    Protic substrates have been used as a reactant with the Ln(C 6 F 5) 2 complex as shown: Ln(C 6 F 5) 2 + 2LH → Ln(L) 2 + 2C 6 F 5 H. It is possible to avoid the challenges of working with the unstable Ln(C 6 F 5) 2 complex by forming it in situ by the following reaction: Ln + HgR 2 + 2 LH → Ln(L) 2 + Hg + 2 RH

  7. Transalkylation - Wikipedia

    en.wikipedia.org/wiki/Transalkylation

    In organic chemistry, transalkylation is a chemical reaction involving the transfer of an alkyl group from one organic compound to another. The reaction is used for the transfer of methyl and ethyl groups between benzene rings.

  8. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    For monoalkenes, the configuration is often indicated by the prefixes cis- (from Latin "on this side of") or trans- ("across", "on the other side of") before the name, respectively; as in cis-2-pentene or trans-2-butene. The difference between cis-and trans-isomers

  9. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
