  2. Tropone - Wikipedia

    en.wikipedia.org/wiki/Tropone

    Tropone or 2,4,6-cycloheptatrien-1-one is an organic compound with some importance in organic chemistry as a non-benzenoid aromatic. [2] The compound consists of a ring of seven carbon atoms with three conjugated alkene groups and a ketone group.

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule.

  4. Tropolone - Wikipedia

    en.wikipedia.org/wiki/Tropolone

    Tropolone is an organic compound with the chemical formula C 7 H 5 (OH)O. It is a pale yellow solid that is soluble in organic solvents. It is a pale yellow solid that is soluble in organic solvents. The compound has been of interest to research chemists because of its unusual electronic structure and its role as a ligand precursor.

  5. Buchner ring expansion - Wikipedia

    en.wikipedia.org/wiki/Buchner_ring_expansion

    In 1998, Mander et al. synthesized the diterpenoid tropone, harringtonolide [6] using the Buchner intramolecular ring expansion annulation chemistry. A rhodium catalyst (Rh 2 (mandelate) 4) and DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) were used to generate the carbene. This natural product was found to have antineoplastic and antiviral properties.

  6. Cycloheptatriene - Wikipedia

    en.wikipedia.org/wiki/Cycloheptatriene

    Cycloheptatriene (CHT) is an organic compound with the formula C 7 H 8. It is a closed ring of seven carbon atoms joined by three double bonds (as the name implies) and four single bonds. This colourless liquid has been of recurring theoretical interest in organic chemistry.

  7. Functionality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Functionality_(Chemistry)

    In chemistry, functionality is the presence of functional groups in a molecule. A monofunctional molecule possesses one functional group, a bifunctional (or difunctional) two, a trifunctional three, and so forth. In organic chemistry (and other fields of chemistry), a molecule's functionality has a decisive influence on its reactivity.

  8. Substituent - Wikipedia

    en.wikipedia.org/wiki/Substituent

    In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. [1] ( In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, [2] though certain ...

  9. Homoaromaticity - Wikipedia

    en.wikipedia.org/wiki/Homoaromaticity

    Homoaromaticity, in organic chemistry, refers to a special case of aromaticity in which conjugation is interrupted by a single sp 3 hybridized carbon atom. Although this sp 3 center disrupts the continuous overlap of p-orbitals, traditionally thought to be a requirement for aromaticity, considerable thermodynamic stability and many of the spectroscopic, magnetic, and chemical properties ...
