oxirane

Treatment with a strong base leads to internal displacement and thus formation of the oxirane.

Research into new areas continued at Halcon after the creation of Oxirane.

Those structures indicated the likely structures of the oxirane precursors.

Many compounds have trivial names, ethylene oxide is called "oxirane."

The epoxide group is also sometimes referred to as a glycidyl or oxirane group.

Evidence for oxirane formation by P450-linked microsomal monooxygenases.

Furthermore, the relaxation data for the oxirane ring carbons do not uniquely define a dynamic model.

The third effect is the ring-opening effect which can be illustrated at the polymerization of oxirane.

Epoxidation of diene 40 with meta-chloroperoxybenzoic acid gave the oxirane ring.

This compound serves as the substrate for reaction with the other dithiane 9 to the oxirane ring opening product 10.

Bent bonds are found in strained organic compounds such as cyclopropane, oxirane and aziridine.

This can be illustrated with the fact that oxirane polymerizes readily while o xolane is by far less reactive.

The oxirane rings of carbohydrate 2,3-anhydro sugars are opened stereospecifically by lithium dimethyl cuprate.

Ring opening of the oxirane with ammonia gives a mixture of the trans amino alcohols (6).

Key words: vibrational circular dichroism, oxirane, chiral perturbation.

Monomers with large ring strain, such as oxirane, are more reactive than 1,3-dioxepane which has considerably less ring strain.

Information on ethylene oxide (also known as 1,2-epoxyethane, oxirane, or dimethylene oxide), for use in responding to chemical incidents.

The first-formed ylide does fragment to carbene and acetone in a second step that competes with oxirane formation.

The data confirm earlier evidence that the oxirane ring is trans, and indicate that 1 is the 6R, 7S diastereomer.

A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline.

Key words: bicyclic ketone, dialkoxycarbene, dialkoxyoxirane, hydroxylactone, "oxirane dimers".

The regioselectivity of the attack was dependent on the transition states, implying weak steric hindrance and a conjugation oxirane – double bond.

It can be formed by the nucleophilic attack of methanol on protonated oxirane followed by proton transfer:

Thermal isomerization yields a ketoacetate with inversion of the configuration by a concerted mechanism if the oxirane does not contain a hydrogen atom.

It consists of phenoxide reacting at the oxirane and resulting in an alkoxide, that displaces the adjacent chloride to form a new epoxide ring.
