Exempel på hur man kan använda ARENE i en mening

• Their structures differ in the arene substitution pattern—the location of the methoxy group on the ring as compared to the acyl halide.
• The Vilsmeier–Haack reaction (also called the Vilsmeier reaction) is the chemical reaction of a substituted formamide (1) with phosphorus oxychloride and an electron-rich arene (3) to produce an aryl aldehyde or ketone (5):.
• In this electrophilic aromatic substitution reaction, the aryldiazonium cation is the electrophile, and the activated carbon (usually from an arene, which is called coupling agent), serves as a nucleophile.
• A Meisenheimer complex or Jackson–Meisenheimer complex in organic chemistry is a 1:1 reaction adduct between an arene carrying electron withdrawing groups and a nucleophile.
• The Scholl reaction is a coupling reaction between two arene compounds with the aid of a Lewis acid and a protic acid.
• Arylsulfonyl chlorides are made industrially in a two-step, one-pot reaction from an arene (in this case, benzene) and chlorosulfuric acid:.
• The arene compound (here benzene) is reacted with a diazonium salt in the presence of a base to provide the biaryl through an intermediate aryl radical.
• where X in the arene compound can be a sulfone, a sulfide, an ether or any substituent capable of dislodging from the arene carrying a negative charge.
• In organic synthesis, directed ortho metalation is widely used for the functionalization of arene rings via C-H activation.
• Hydrogenation of the arene ring in the indenyl ligand resulted in CO substitution at about half the rate of the cyclopentadienyl compound.
• An arylene or arenediyl is a substituent of an organic compound that is derived from an aromatic hydrocarbon (arene) and is bivalent, such as phenylene.
• Kekulé used evidence that had accumulated in the intervening years—namely, that there always appeared to be only one isomer of any monoderivative of benzene, and that there always appeared to be exactly three isomers of every disubstituted derivative—now understood to correspond to the ortho, meta, and para patterns of arene substitution—to argue in support of his proposed structure.
• Superphane is a 6-fold bridged cyclophane with all arene positions in the benzene dimer taken up by ethylene spacers.
• Ogoshi and Kanai decided naming the new family of host macrocycles "pillararene", since they are cylindrical or pillar-like in shape and composed of aromatic or "arene" moieties.
• This step leads to the formation of a positively charged and delocalized cyclohexadienyl cation, also known as an arenium ion, Wheland intermediate, or arene σ-complex (2b).
• Lucilla de Lachenal, "Biografia di Luigi Bernabò Brea", in Dalle arene candide a Lipari, Roma 2004, pp.
• Types of carbocyclic arene dearomization include hydrogenative (Birch reduction), alkylative, photochemical, thermal, oxidative, transition metal-assisted and enzymatic.
• In this reaction, an aryl halide (usually iodide or bromide) exchanges with organolithium to form a lithiated arene species.
• For the bromination (with NBS) and iodination (with NIS), the reaction is highly chemoselective, with halogenation solely taking place at C–Ge in presence of electron-rich arene, heterocycle substrates or other reactive functional groups.
