Reaction of dialkyl zinc compounds with alkyl halides to form hydrocarbons; may be used to form paraffins containing a quaternary carbon atom.
Industry:Chemistry
A method for preparation of cycloparaffins in which dihalo derivatives of the paraffins are treated with zinc to produce the cycloparaffin.
Industry:Chemistry
A substitution reaction, catalyzed by aluminum chloride in which an alkyl (R_) or an acyl (RCO_) group replaces a hydrogen atom of an aromatic nucleus to produce hydrocarbon or a ketone.
Industry:Chemistry
A synthesis of quinolines; the method is usually catalyzed by bases and consists of condensation of an aromatic o-amino-carbonyl derivative with a compound containing a methylene group in the alpha position to the carbonyl.
Industry:Chemistry
The conversion of a phenolic ester into the corresponding o- and p-hydroxyketone by treatment with catalysts of the type of aluminum chloride.
Industry:Chemistry
The rule that the most stable form of the bonds of a polynuclear compound is that arrangement which has the maximum number of rings in the benzenoid form, that is, three double bonds in each ring.
Industry:Chemistry
A synthesis of primary amines by the hydrolysis of Nalkylphthalimides; the latter are obtained from potassium phthalimide and alkyl halides.
Industry:Chemistry
1. Reaction of a phenol or phenol ester, and hydrogen chloride or hydrogen cyanide, in the presence of a metallic chloride such as aluminum chloride to form, after hydrolysis, an aldehyde. 2. Reaction of an aqueous ethanolic solution of diazonium salts with precipitated copper powder or other reducing agent to form diaryl compounds.
Industry:Chemistry
(CH<sub>3</sub>)<sub>2</sub>C(C<sub>6</sub>H<sub>5</sub>OH)<sub>2</sub> Brown crystals that are insoluble in water; used in the production of phenolic and epoxy resins.
Industry:Chemistry
The rule that glutaric and succinic acids yield cyclic anhydrides on pyrolysis, while adipic and pimelic acids yield cyclic ketones; there are certain exceptions.
