    Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene01:13

    Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

    Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

    Diazonium Group Substitution with Halogens and Cyanide: Sandmeyer and Schiemann Reactions

    Arenediazonium substitution reactions occur when the diazonium group is substituted by various functional groups such as halides, hydroxyl, nitrile, etc. For instance, arenediazonium salts react with copper(I) salts of chloride, bromide, or cyanide to form corresponding aryl chlorides, bromides, and nitriles. These reactions are named Sandmeyer reactions. Although the mechanism of this reaction is complicated, as illustrated in Figure 1, they are believed to progress via an aryl copper...
    Preparation and Reactions of Sulfides02:26

    Preparation and Reactions of Sulfides

    Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
    Nucleophilic Aromatic Substitution of Aryldiazonium Salts: Aromatic SN101:14

    Nucleophilic Aromatic Substitution of Aryldiazonium Salts: Aromatic SN1

    Treating arylamines with nitrous acid gives aryldiazonium salts that are effective substrates in nucleophilic aromatic substitution reactions. The diazonio group in these salts can be easily displaced by different nucleophiles, yielding a wide variety of substituted benzenes. The leaving group departs as nitrogen gas, and this easy elimination is the driving force for the substitution reaction.
    In the Sandmeyer reaction, for example, the diazonio group is replaced by a chloro, bromo, or cyano...
    Alkyl Halides02:45

    Alkyl Halides

    Structural Properties
    Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
    Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
    Nomenclature of Aromatic Compounds with Multiple Substituents01:11

    Nomenclature of Aromatic Compounds with Multiple Substituents

    When more than one substituent is present on the benzene ring, the IUPAC nomenclature depends on the number of substituents present.
    For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
