Alkoxymercuration
|
Addition of mercury and an alkoky group to a double bond, usually by a solution of mercuric acetate in an alcohol, usually followed by sodium borohydride reduction to give an ether.
ALKENE--Hg(OAc)2/alcohol--NaBH4--ETHER |
|
|
Alpha cleavage
|
the breaking of a bond between the first and second carbon atoms adjacent to the ether oxygen atom (or other functional group)
(618 |
|
|
Autooxidation
|
any oxidation that proceeds spontaneously using the oxygen in the air. Autooxiation of ethers gives hydroperoxides and dialkyl peroxides.
|
|
|
Concerted Reaction
|
A reaction that takes place in one step, with simultaneous bond breaking and bond forming.
|
|
|
Crown Ether
|
a large cyclic polyether used to complex and solvate cations in nonpolar solvents.
|
|
|
Dioxane
|
a heterocyclic ether with 2 oxygen atoms in a six-membered ring.
|
|
|
Epoxidation
|
Oxidation of an alkene to an epoxide. Usually accomplished by treating the aleken with a peroxyacid.
|
|
|
Epoxide (oxirane)
|
a compound containing a 3-membered heterocyclic ether.
|
|
|
Ether
|
R--O--R'
|
|
|
symmetrical ether
|
an ether with 2 identical alkyl groups
|
|
|
Furan
|
the 5-membered heterocyclic ether with 2 carbon-carbon double bonds.
|
|
|
Halohydrin
|
a compound containing a halogen atom and a hydroxyl group on adjacent carbon atoms.
|
|
|
Heterocyclic compound
|
a compound containing a ring in which one or more of the ring atoms are elements other than carbon.
|
|
|
MCPBA
|
meta-chloroperoxybenzoic acid, and epoxidizing agent.
|

oxane
|
systematic name for a 6-membered cyclic ether (a tetrohydropyran).
|
|
|
Oxetane
|
4-membered heterocyclic ether
|
|
|
Oxirane
|
an epoxide or for ethylene oxide specifically. 3-membered ether
|
|
|
Oxolane
|
5-membered cyclic ether (a tetrahydrofuran).
|
|
|
Peroxide
|
any compound containing the
--O--O-- linkage. The oxygen-oxygen bond is easily cleaved, and organic peroxides are prone to explosions. |
|
|
hydrogen peroxide
|
H--O--O--H
|
|
|
alkyl hydroperoxide
|
R--O--O--H
|
|
|
dialkyl peroxide

|
|
|
Peroxyacid
|
a carboxylic acid with an extra oxygen in the hydroxyl group.
R--C(=0)--O--O--H |
|
|
Pyran
|
6-membered heterocyclic ether with 2 carbon-carbon double bonds
|
|
|
Williamson Ether Synthesis
