  2. Trichloroethyl chloroformate is used in organic synthesis for the introduction of the trichloroethyl chloroformate (Troc) protecting group for amines, thiols and alcohols.It readily cleaves vs other carbamates and can be used in an overall protecting group strategy.

  3. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acid ), as part of many larger functional groups.

    (R)-α-methoxy-α-(trifluoromethyl)- phenylacetic acid (Mosher's acid). In analytical chemistry, a chiral derivatizing agent (CDA), also known as a chiral resolving reagent, is a derivatization reagent that is a chiral auxiliary used to convert a mixture of enantiomers into diastereomers in order to analyze the quantities of each enantiomer present and determine the optical purity of a sample.

  6. Absolute configuration - Wikipedia

    en.wikipedia.org/wiki/Absolute_configuration

    In chemistry, absolute configuration refers to the spatial arrangement of atoms within a molecular entity (or group) that is chiral, and its resultant stereochemical description. [1] Absolute configuration is typically relevant in organic molecules where carbon is bonded to four different substituents .

  7. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.

  8. Magnetic inequivalence - Wikipedia

    en.wikipedia.org/wiki/Magnetic_inequivalence

    Magnetic inequivalence may occur with H 2 C-CH 2 fragments that are subdivided into two groups of two in either geminal relationships via a mirror plane along the C-C bond, i.e. H A H A′ C-CH B H B′, or in vicinal relationships via a mirror plane bisecting the C-C bond, i.e. in H A H B C-CH A′ H B′, [4] or via a rotational axis of ...

  9. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    Unsaturated compounds generally carry out typical addition reactions that are not possible with saturated compounds such as alkanes. A saturated organic compound has only single bonds between carbon atoms. An important class of saturated compounds are the alkanes. Many saturated compounds have functional groups, e.g., alcohols.
