  2. Benzenesulfonyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzenesulfonyl_chloride

    The compound is prepared by the chlorsulfonation of benzene: C 6 H 6 + 2SHO 3 SCl → C 6 H 5 SO 2 Cl + HCl + SO 3. Benzenesulfonic acid is an intermediate in this conversion. Diphenylsulfone is a side product. Benzenesulfonyl chloride can also be prepared by treating benzenesulfonate salts with phosphorus oxychloride. [2]

  3. Anisole - Wikipedia

    en.wikipedia.org/wiki/Anisole

    Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites.

  4. Benzenesulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Benzenesulfonic_acid

    Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S.It is the simplest aromatic sulfonic acid.It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether.

  5. Alkoxy group - Wikipedia

    en.wikipedia.org/wiki/Alkoxy_group

    Alkoxy groups Aryloxy groups. 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]

  6. Sulfonyl halide - Wikipedia

    en.wikipedia.org/wiki/Sulfonyl_halide

    The sulfonyl chlorides and fluorides are of dominant importance in this series. [1] [2] Sulfonyl halides have tetrahedral sulfur centres attached to two oxygen atoms, an organic radical, and a halide. In a representative example, methanesulfonyl chloride, the S=O, S−C, and S−Cl bond distances are respectively 142.4, 176.3, and 204.6 pm. [3]

  7. Proton nuclear magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Proton_nuclear_magnetic...

    Simple molecules have simple spectra. The spectrum of ethyl chloride consists of a triplet at 1.5 ppm and a quartet at 3.5 ppm in a 3:2 ratio. The spectrum of benzene consists of a single peak at 7.2 ppm due to the diamagnetic ring current. Together with carbon-13 NMR, proton NMR is a powerful tool for molecular structure characterization.

  8. Sulfonamide - Wikipedia

    en.wikipedia.org/wiki/Sulfonamide

    It consists of a sulfonyl group (O=S=O) connected to an amine group (−NH 2). Relatively speaking this group is unreactive . Because of the rigidity of the functional group, sulfonamides are typically crystalline ; for this reason, the formation of a sulfonamide is a classic method to convert an amine into a crystalline derivative which can be ...

  9. Sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfonic_acid

    General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.
