The tautomerism of the norcaradiene and cycloheptatriene can be understood based on the Walsh cyclopropane molecular orbitals of the norcaradiene cyclopropane ring.

43.
Finally, an unusual ER catalyzed cyclization reaction, purported to go through a substitution like mechanism, forms the cyclopropane ring.
44.
Photolysis of "'2 "'results in the initial formation of an biradical intermediate with a cyclopropane ring formed.
45.
The simplest alicyclic compounds are the monocyclic cycloalkanes : cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, and so on.
46.
Subsequent to this, the cyclopropane ring is opened with cycloeucalenol cycloisomerase ( E3 ) to form "'10 " '.
47.
Ring strain is highest for cyclopropane, in which the carbon atoms form a triangle and therefore have 60 degree C C C bond angles.
48.
When the cyclopropane ring is fitted with a 2-vinyl group, a cyclopentadiene is formed through a so-called foiled carbene intermediate.
49.
He was able to synthesise enough cyclopropane to do several chemical reactions and derive from the results the three-membered ring structure of cyclopropane.
