  2. Aryl group - Wikipedia

    en.wikipedia.org/wiki/Aryl_group

    The simplest aryl group is phenyl, which is made up of a benzene ring with one of its hydrogen atom replaced by some substituent, and has the molecular formula C 6 H 5 −. Note that a phenyl group is not the same as a benzyl group, the latter consisting of a phenyl group attached to a methyl group and a molecular formula of C 6 H 5 CH 2 − ...

  3. Phenyl group - Wikipedia

    en.wikipedia.org/wiki/Phenyl_group

    In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

  4. Alkoxy group - Wikipedia

    en.wikipedia.org/wiki/Alkoxy_group

    In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1] An ethoxy group (CH 3 CH 2 O−) is found in the organic compound ethyl phenyl ether (C 6 H 5 OCH 2 CH 3, also known as ethoxybenzene).

  5. Aryl radical - Wikipedia

    en.wikipedia.org/wiki/Aryl_radical

    An aryl radical in organic chemistry is a reactive intermediate and an arene compound incorporating one free radical carbon atom as part of the ring structure. As such it is the radical counterpart of the arenium ion. The parent compound is the phenyl radical C 6 H • 5. [1] Aryl radicals are intermediates in certain organic reactions.

  6. Aryl halide - Wikipedia

    en.wikipedia.org/wiki/Aryl_halide

    Aryl halides are distinct from haloalkanes (alkyl halides) due to significant differences in their methods of preparation, chemical reactivity, and physical properties. The most common and important members of this class are aryl chlorides, but the group encompasses a wide range of derivatives with diverse applications in organic synthesis ...

  7. Fries rearrangement - Wikipedia

    en.wikipedia.org/wiki/Fries_rearrangement

    In addition to the ordinary thermal phenyl ester reaction a photochemical variant is possible. The photo-Fries rearrangement can likewise give [1,3] and [1,5] products, [7] [8] which involves a radical reaction mechanism. This reaction is also possible with deactivating substituents on the aromatic group. Because the yields are low this ...

  8. Benzyl group - Wikipedia

    en.wikipedia.org/wiki/Benzyl_group

    The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2. None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction ...

  9. Methylenedioxy - Wikipedia

    en.wikipedia.org/wiki/Methylenedioxy

    Methylenedioxy is the term used in the field of chemistry, particularly in organic chemistry, for a functional group with the structural formula R-O-CH 2-O-R' which is connected to the rest of a molecule by two chemical bonds. The methylenedioxy group consists of two oxygen atoms connected to a methylene bridge (-CH 2 - unit).
