  2. Bicyclobutane - Wikipedia

    en.wikipedia.org/wiki/Bicyclobutane

    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]

  3. Bicyclic molecule - Wikipedia

    en.wikipedia.org/wiki/Bicyclic_molecule

    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.

  4. Cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Cycloalkane

    Norbornane (also called bicyclo[2.2.1]heptane). Unsubstituted cycloalkanes that contain a single ring in their molecular structure are typically named by adding the prefix "cyclo" to the name of the corresponding linear alkane with the same number of carbon atoms in its chain as the cycloalkane has in its ring.

    en.wikipedia.org/wiki/Chemical_graph_generator

    By extending the molecule with a bond, an intermediate structure is built. Each intermediate structure can be represented by a node in the generation tree. ASSEMBLE was developed with a user-friendly interface to facilitate use. The second version of ASSEMBLE was released in 2000. [13] Another assembly method is GENOA. [14]
