Term
An __________ refers to a reaction that forms a carbon-oxygen bond (__________ are oxidizing agents, and the addition of a halogen molecule across a double bond is formally an __________ as well).
Definition
1) Oxidation
2) Halogens
3) Oxidation
Term
Oxidations are particularly important because many common __________ __________ contain oxygen, and alkene oxidations are some of the best methods for introducing __________ into organic molecules.
Definition
1) Functional groups
2) Oxygen
Term
An __________ is a three-membered cyclic ether, also called an __________.
Definition
1) Epoxide
2) Oxirane
Term
__________ are valuable synthetic intermediates used for converting __________ to a variety of other functional groups.
Definition
1) Epoxides
2) Alkenes
Term
An alkene is converted to an epoxide by a __________, a carboxylic acid that has an extra __________ atom in a -O-O- (__________) linkage.
Definition
1) Peroxyacid
2) Oxygen
3) Peroxy
Term
The __________ of an alkene is clearly an oxidation, since an __________ atom is added.
Definition
1) Epoxidation
2) Oxygen
Term
__________ are highly selective oxidizing agents.
Definition
1) Peroxyacids
Term
A __________ epoxidizes an alkene by a __________ electrophilic reaction where several bonds are broken and formed simultaneously.
Starting with the alkene and the peroxyacid, a one-step reaction gives the __________ and the __________ directly, without any intermediates.
Definition
1) Peroxyacid
2) Concerted
3) Epoxide
4) Acid
Term
*Mechanism 8-9: Epoxidation of Alkenes*
__________ epoxidize alkenes in a one-step (__________) process.
Definition
1) Peroxyacids
2) Concerted
Term
Since the __________ takes place in one step, there is no opportunity for the alkene molecule to rotate and change its __________ or __________ geometry; the __________ retains whatever stereochemistry is present in the alkene.
Definition
1) Epoxidation
2) Cis
3) Trans
4) Epoxide
