A vinyl halide is clearly a species with a formula h 2c c x h in which a halide is directly bound to an olefinic bond formally this is ethylene h 2c ch 2 with one of the hydrogens substituted by a heteroatom vinyl chloride h 2c chcl is an example.
This lack of reactivity is due to several factors.
The simplest way to draw the structure of chlorobenzene is.
For 3º halides a very slow s n 2 substitution or if the nucleophile is moderately basic e2 elimination.
Likewise phenyl cations are unstable thus making s n 1 reactions impossible.
They are indeed starting materials for a range of metal mediated cross coupling reactions such as just to mention a few the heck stille suzuki miyaura sonogashira linstrumelle tsuji 2005 or ullmann goldberg evano and blanchard 2013 reactions that are used on a daily basis in most.

Ethers are a class of organic compounds that contain an ether group an oxygen atom connected to two alkyl or aryl groups.
Alexanian the catalytic aminocarbonylation of hetero aryl halides is widely applied in the synthesis of amides but relies heavily on the use of precious metal catalysis.
We ll look in some detail at the structure of chlorobenzene.
Aryl halides are relatively unreactive toward nucleophilic substitution reactions.
Nucleophilic substitution in the aryl halides.
If the alkyl groups are the same on both sides of the oxygen atom then it is a simple or symmetrical ether whereas if they.
