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. Cyclobutane itself is of no commercial or biological significance, but more complex derivatives are important in biology and ...
Ball-and-stick model of cyclobutane In organic chemistry , the cycloalkanes (also called naphthenes , but distinct from naphthalene ) are the monocyclic saturated hydrocarbons . [ 1 ] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains ), and all of ...
The prismanes are a class of hydrocarbon compounds consisting of prism-like polyhedra of various numbers of sides on the polygonal base. Chemically, it is a series of fused cyclobutane rings (a ladderane, with all-cis/all-syn geometry) that wraps around to join its ends and form a band, with cycloalkane edges.
Kischner synthesized cyclobutanone from cyclobutanecarboxylic acid. The Russian chemist Nikolai Kischner first prepared cyclobutanone in a low yield from cyclobutanecarboxylic acid.
Acyclic aliphatic/non-aromatic compound Cyclic aliphatic/non-aromatic compound (cyclobutane)In organic chemistry, hydrocarbons (compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (/ ˌ æ l ɪ ˈ f æ t ɪ k /; G. aleiphar, fat, oil).
Cyclobutane is a larger ring, but still has bent bonds. In this molecule, the carbon bond angles are 90° for the planar conformation and 88° for the puckered one. Unlike in cyclopropane, the C–C bond lengths actually increase rather than decrease; this is mainly due to 1,3-nonbonded steric repulsion.
The naming of polycyclic alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings (e.g., "bicyclo"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of vertices.
The final cyclobutane is formed by a Wolff rearrangement, and the alkyl chain is installed by a Wittig olefination. Synthesis of [5]-ladderane lipid pentacycloannamoxic acid In 2016, Burns and co-workers at Stanford University reported an enantioselective synthesis of both the [3]- and [5]-ladderane lipid tails and their incorporation into a ...
