Bicyclobutane is noted for being one of the most strained compounds that is isolatable on a large scale — its strain energy is estimated at 63.9 kcal mol −1. It is a nonplanar molecule, with a dihedral angle between the two cyclopropane rings of 123°.
Bicyclobutane was prepared this way from 1-bromo-3-chlorocyclobutane in 95% yield. The reaction is conducted in refluxing dioxane, at which temperature, the sodium is liquid. The reaction is conducted in refluxing dioxane, at which temperature, the sodium is liquid.
The numbers are sometimes omitted in unambiguous cases. For example, bicyclo[1.1.0]butane is typically called simply bicyclobutane. The heterocyclic molecule DABCO has a total of 8 atoms in its bridged structure, hence the root name octane. Here the two bridgehead atoms are nitrogen instead of carbon atoms.
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.
This category was created to provide a "home" for inorganic compounds (such as NaBH 4) that are widely used in stoichiometric quantities in organic chemistry, but widely used organic reagents (such as oxalyl chloride) may belong here also.

N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis.
9-Borabicyclo[3.3.1]nonane or 9-BBN is an organoborane compound. This colourless solid is used in organic chemistry as a hydroboration reagent.The compound exists as a hydride-bridged dimer, which easily cleaves in the presence of reducible substrates.
