3-Quinolinecarbonitrile, 2,4-dichloro-

3-Quinolinocarbonitrile, 2,4-dichloro-The chemical properties of this substance are as follows:
Its appearance may be solid, because it contains a cyanide group (-CN) and a chlorine atom, it has certain chemical activity. The cyanide group can undergo various reactions. For example, under appropriate conditions, it can be hydrolyzed to form a carboxyl group, that is, -CN can be converted to -COOH. This hydrolysis reaction usually needs to be carried out under the catalysis of acid or base. The two chlorine atoms in the
molecule are also active reaction check points. In nucleophilic substitution reactions, chlorine atoms are easily replaced by other nucleophiles. For example, in the presence of suitable nucleophiles such as alkoxides (RO), chlorine atoms can be replaced by alkoxy (-OR) to form alkoxy-containing derivatives.
Since the quinoline ring is an aromatic system, it endows the compound with certain stability and special electronic effects. The aromatic ring can undergo electrophilic substitution reactions such as halogenation, nitration, sulfonation, etc. Since chlorine atoms are already occupied at the 2,4-positions, the electrophilic substitution reaction may mainly occur at other locations with suitable electron cloud densities on the quinoline ring.
This compound may also participate in metal-catalyzed reactions, such as palladium-catalyzed coupling reactions. In the presence of specific palladium catalysts and ligands, its chlorine atoms can be coupled with other organometallic reagents to construct more complex organic structures.
