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 ...
Cyclobutane dimer (CPD) (left), 6,4-dimer (6-4PP) (right) Pyrimidine dimers encompass several types, each with distinct structures and implications for DNA integrity. [citation needed] Cyclobutane pyrimidine dimer (CPD) is a dimer which features a four-membered ring formed by the fusion of two double-bonded carbons from adjacent pyrimidines.
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 ...
This synthesis resembles the method used to produce CBDO today. The first step involves conversion of the isobutyric acid or its anhydride into the ketene. This ketene then dimerizes to form a four-membered ring with two ketone groups. The product ring is hydrogenated to give a diol.

For example, the oxidative decarboxylation of cyclobutanecarboxylic acid was improved by the use of other reagents and methods. A newer, more efficient preparation of cyclobutanone was found by P. Lipp and R. Köster in which a solution of diazomethane in diethyl ether is reacted with ketene . [ 5 ]
Benzocyclobutene (BCB) is a benzene ring fused to a cyclobutane ring. It has chemical formula C 8 H 8. [1]BCB is frequently used to create photosensitive polymers.BCB-based polymer dielectrics may be spun on or applied to various substrates for use in Micro Electro-Mechanical Systems (MEMS) and microelectronics processing.
