  2. Bicyclobutane - Wikipedia

    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.

    en.wikipedia.org/wiki/Diradicaloid

    Cyclobutane-1,3-diyl is the planar four-membered carbon ring species with radical character localized at the 1 and 3 positions. The singlet cyclobutane-1,3-diyl is predicted to be the transition state for the ring inversion of bicyclobutane, proceeding via homolytic cleavage of the transannular carbon-carbon bond (Figure 3).

  4. Bicyclic molecule - Wikipedia

    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.

  5. Wurtz reaction - Wikipedia

    en.wikipedia.org/wiki/Wurtz_reaction

    The RM intermediates have been isolated in several cases. The radical is susceptible to diverse reactions. The organometallic intermediate (RM) next reacts with the alkyl halide (RX) forming a new carbon–carbon covalent bond. RM + RX → R−R + MX. The process resembles an S N 2 reaction, but the mechanism is probably complex.

  6. Reaction intermediate - Wikipedia

    en.wikipedia.org/wiki/Reaction_intermediate

    In chemistry, a reaction intermediate, or intermediate, is a molecular entity arising within the sequence of a stepwise chemical reaction. It is formed as the reaction product of an elementary step , from the reactants and/or preceding intermediates, but is consumed in a later step.

  7. Cyclobutanecarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Cyclobutanecarboxylic_acid

    Cyclobutanecarboxylic acid is an intermediate in organic synthesis. For example, it is a precursor to cyclobutylamine. [3] References This page was last edited on 11 ...

  8. Cycloalkane - Wikipedia

    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.
