Exempel på hur man kan använda DISUBSTITUTED i en mening

• The Larock indole synthesis is a heteroannulation reaction that uses palladium as a catalyst to synthesize indoles from an ortho-iodoaniline and a disubstituted alkyne.
• Monosubstituted hydrazines and so-called asymmetrically disubstituted hydrazines, where (only) two hydrocarbon groups are bonded to the same nitrogen atom are colorless liquids.
• Procainamide is a classical bioisostere because the valence electron structure of a disubstituted oxygen atom is the same as a trisubstituted nitrogen atom, as Langmuir showed.
• A molozonide (or "molecular ozonide") is a 1,2,3-trioxolane, which can also be considered a cyclic disubstituted trioxidane derivative.
• A variety of substituted 1,3-Cyclobutanediones form upon spontaneous dimerization of disubstituted ketenes.
• 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.
• Euglenophycin produced by euglenoids is a disubstituted piperidine as it is constituted of a piperidine ring with a butanol side chain at the 6th position and a (1E,3E,7Z)-1,3,7-undecatriene side chain at the 2nd position.
• in 1994, in which an alkynyl substituted β-ketoester was treated with cyclopentadienyl cobalt complex and irradiation to give disubstituted methylene cyclopentane.
• Reductive cyclization of the subsequent product using hexamethyldisilazane, zinc chloride and dimethylformamide forms the disubstituted heterocycle present in the (−)-phaitantrin D molecule.
• Examples include geminal disubstituted alkanes, such as 1,1-dichloroethane being known as ethylidene dichloride (compare 1,2-dichloroethane's common name of ethylene dichloride); and cyclic ketals such as solketal and Meldrum's acid, also known respectively as isopropylidene glycerol and isopropylidene malonate.
