Ethylene oxide, the simplest epoxide, is an intermediate in the manufacture of both ethylene glycol, used for automobile antifreeze, and polyester polymers. More than 4 million tons of ethylene oxide is produced each year in the United States by air oxidation of ethylene over a silver oxide catalyst at 300 °C. This process is not useful for other epoxides, however, and is of little value in the laboratory. Note that the name ethylene oxide is not a systematic one because the -ene ending implies the presence of a double bond in the molecule. The name is frequently used, however, because ethylene oxide is derived pom ethylene by addition of an oxygen atom. Other simple epoxides are named similarly. The systematic name for ethylene oxide is 1,2-epoxyethane. 

Treatment of 1,1-diphenyl-1,2-epoxyethane with aqueous acid yields diphenylacetaldehyde as the major product. Propose a mechanism for the reaction. 

In contrast, a number of alkene epoxides (10.3) are chemically quite stable, i.e., intrinsically less reactive than arene oxides. Examples of epoxide metabolites that have proven to be stable enough to be isolated in the absence of degrading enzymes include 1,2-epoxyoctane (10.4), 1,2-epoxycyclohex-ane (10.5), 1-phenyl-1,2-epoxy ethane (styrene oxide, 10.6), and cis- 1,2-diphenyl-1,2-epoxyethane (cfv-stilbene oxide, 10.7) [12], The same is true of alclofenac epoxide (10.8), hexobarbital epoxide (10.9), and a few other epoxides of bioactive compounds.

The synthesis of epoxy ethers by peroxy acid treatment of suitable vinylic ethers, on the other hand, is complicated by the acid sensitivity of epoxy ethers. For example, Bergmann and Mk>keley1Ss claimed in 1921 to have prepared 1 -ethoxy-1 (2 -epoxyethane by the oxidation of ethyl vinyl ether with perbenzoic aoid, bat B years later modified their structure to a dioxone type of dimer.186 In 1 B0 Mous-seron and co-wcrkere1168-1184 reported the preparation of an epoxy ether from 1 -ethoxy-1 -eydohexene, but 4 years later Stevens and Taznma164 showed the compound obtained in this oxidation, not to have the structure initially assigned to it.
