The intermediate 1-bromo-3-chlorocyclobutane can also be prepared via a modified Hunsdiecker reaction from 3-chlorocyclobutanecarboxylic acid using mercuric oxide and bromine: [4] A synthetic approach to bicyclobutane derivatives involves ring closure of a suitably substituted 2-bromo-1-(chloromethyl)cyclopropane with magnesium in THF. [5]
For example, the carbon frame of norbornane contains a total of 7 atoms, hence the root name heptane. This molecule has two paths of 2 carbon atoms and a third path of 1 carbon atom between the two bridgehead carbons, so the brackets are filled in descending order: [2.2.1]. Addition of the prefix bicyclo gives the total name bicyclo[2.2.1]heptane.
In alkanes, optimum overlap of atomic orbitals is achieved at 109.5°. The most common cyclic compounds have five or six carbons in their ring. [6] Adolf von Baeyer received a Nobel Prize in 1905 for the discovery of the Baeyer strain theory, which was an explanation of the relative stabilities of cyclic molecules in 1885.
Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia. Do not translate text that appears unreliable or low-quality.
Cyclobutane is a cycloalkane and organic compound with the formula (CH 2) 4.Cyclobutane is a colourless gas and is commercially available as a liquefied gas.Derivatives of cyclobutane are called cyclobutanes.

Cyclobutanecarboxylic acid is an intermediate in organic synthesis. For example, it is a precursor to cyclobutylamine. For example, it is a precursor to cyclobutylamine. [ 3 ]
The Stetter reaction is a reaction used in organic chemistry to form carbon-carbon bonds through a 1,4-addition reaction utilizing a nucleophilic catalyst. [1] While the related 1,2-addition reaction, the benzoin condensation, was known since the 1830s, the Stetter reaction was not reported until 1973 by Dr. Hermann Stetter. [2]
