Oxirene
Encyclopedia
Oxirene is a heterocyclic
hypothesized chemical compound which contains an unsaturated
three-membered ring containing two carbon atoms and one oxygen atom. As the configuration is extremely strained, no consensus exists whether the structure constitutes a molecule or whether it is merely a transition state
. The substance is therefore mainly evaluated by molecular modeling techniques.
Experimental indications exist that oxirene (as intermediate or transition state) occurs in the Wolff rearrangement

Heterocyclic compound
A heterocyclic compound is a cyclic compound which has atoms of at least two different elements as members of its ring. The counterparts of heterocyclic compounds are homocyclic compounds, the rings of which are made of a single element....

In chemistry, saturation has six different meanings, all based on reaching a maximum capacity...

Transition state
The transition state of a chemical reaction is a particular configuration along the reaction coordinate. It is defined as the state corresponding to the highest energy along this reaction coordinate. At this point, assuming a perfectly irreversible reaction, colliding reactant molecules will always...

Wolff rearrangement
The Wolff rearrangement is a rearrangement reaction converting a α-diazo-ketone into a ketene. This reaction was first reported by Ludwig Wolff in 1912....
