Cyclooctyne is the cycloalkyne with a formula C
8H
12. Its molecule has a ring of 8 carbon atoms, connected by seven single bonds and one triple bond.

Cyclooctyne is the smallest cycloalkyne that is stable enough to be isolated, although the chemical is still highly reactive. The alkyne region of the structure attempts to adopt a linear molecular geometry, but the nature of the ring creates substantial ring strain. As a result, cyclooctyne and other compounds containing this ring structure readily react in ways that reduce the ring strain by converting the alkyne to a functional group that does not require linear geometry. An important application of this reactivity is in click chemistry, where cyclooctynes undergo cycloaddition reactions with azides[1] or nitrones,[2] forming triazoles or isoxazolines, respectively.

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
