Vinyl substituted cyclopropanes are readily accessible inter mediates that are commonly used in synthesis 1 release of the cyclopropane ring strain provides a driving force for a variety of radical2 and metal mediated3 transformations.
The total ring strain in cyclopropane is 114 kj mole 1 this strain energy is not exclusively angle strain which results from weaker bonds formed by.
The mechanistic discussion on whether the vinylcyclopropane rearrangement proceeds through a diradical mediated two step or a fully concerted orbital symmetry controlled mechanism has been going on for more than half a century.

It is strained because the bent carbon carbon bonds overlap poorly.
Cyclopropane is the cycloalkane with the molecular formula c 3 h 6 consisting of three carbon atoms linked to each other to form a ring with each carbon atom bearing two hydrogen atoms resulting in d 3h molecular symmetry the small size of the ring creates substantial ring strain in the structure.
Cyclopropane is an anaesthetic in modern anaesthetic practice it has been superseded by other.
