  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. 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.

  4. 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.

  5. Functionality (chemistry) - Wikipedia

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

    In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)

  6. 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.

  7. Cycloheptatriene - Wikipedia

    en.wikipedia.org/wiki/Cycloheptatriene

    This colourless liquid has been of recurring theoretical interest in organic chemistry. It is a ligand in organometallic chemistry and a building block in organic synthesis . Cycloheptatriene is not aromatic , as reflected by the nonplanarity of the methylene bridge (-CH 2 -) with respect to the other atoms; however the related tropylium cation is.

  8. Retrosynthetic analysis - Wikipedia

    en.wikipedia.org/wiki/Retrosynthetic_analysis

    Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method.

  9. Building block (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Building_block_(chemistry)

    Building block is a term in chemistry which is used to describe a virtual molecular fragment or a real chemical compound the molecules of which possess reactive functional groups. [1] Building blocks are used for bottom-up modular assembly of molecular architectures: nano-particles , [ 2 ] [ 3 ] metal-organic frameworks , [ 4 ] organic ...
