What is Hydroarylation?
Hydroarylation can be defined as the addition of an aryl group and a hydrogen atom across an unsaturated moiety (either alkene or alkyne) yielding a new Csp2–Csp3 or Csp2–Csp2 bond, respectively.
How alkynes are formed?
Alkynes are frequently prepared through a double E2 reaction using 2 halides that are vicinal (meaning on adjacent carbons) or geminal (meaning on the same carbon). Because the E2 reaction takes place twice 2 π bonds are formed thus creating an Alkyne.
Where are alkynes found?
The alkyne is an important chemical functional moiety found in numerous natural products widely distributed in terrestrial bacteria, fungi, insects, and plants.
What products contain alkyne?
Alkynes occur in some pharmaceuticals, including the contraceptive noretynodrel. A carbon–carbon triple bond is also present in marketed drugs such as the antiretroviral Efavirenz and the antifungal Terbinafine. Molecules called ene-diynes feature a ring containing an alkene (“ene”) between two alkyne groups (“diyne”).
What are examples of alkyne?
Ethyne is used to make a variety of other compounds. The following are a few examples of these applications: Ethyne is most commonly used to make organic compounds such as ethanol, ethanoic acid, and acrylic acid.

What is an alkyne group?
Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of CnH2n−2. They are unsaturated hydrocarbons. Like alkenes have the suffix –ene, alkynes use the ending –yne; this suffix is used when there is only one alkyne in the molecule.
How do you name an alkyne?
Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.
