2 + -Quinoline formonitrile, its physical properties are as follows:
This substance is mostly crystalline solid at room temperature, and the texture is relatively solid. Looking at its appearance, it is often white to light yellow, with pure color and no variegated mottles. Its crystalline morphology is regular, the crystal surface is flat and shiny, shining shimmering like a fine gem, showing a regular crystal structure.
2 + -quinoline formonitrile has a high melting point, about 160-165 ° C. It requires a higher temperature to melt from a solid state to a liquid state. This characteristic is due to the strong interaction force between molecules, which makes the lattice structure stable and has strong resistance to thermal motion. The boiling point of
is also considerable, roughly in the range of 370-380 ° C. Such a high boiling point indicates that a large amount of energy is required to transform it from liquid to gaseous state. This is due to the intermolecular force not only maintaining the structure in the solid state, but also in the liquid state, which prevents the molecules from escaping the liquid phase.
Its density is higher than that of common organic solvents, about 1.2-1.3 g/cm ³. When placed in water, it will sink to the bottom of the water, because the density is greater than that of water.
In terms of solubility, in common organic solvents such as ethanol, chloroform, and dichloromethane, 2 + -quinoline formonitrile exhibits good solubility and can be uniformly mixed with these solvents to form a clear solution, just like fish entering water, and the phase is fused infinitely. However, the solubility in water is extremely low and almost insoluble. This is because the polarity of 2 + -quinoline formonitrile molecules is very different from that of water molecules, and the principle of "water-oil incompatibility" is also applicable here.
2 + -quinoline formonitrile has a certain refractive index, which is closely related to its molecular structure and electron cloud distribution. This property can be used for identification and purity analysis, providing important clues for exploring its true face.

The chemical properties of 2 + -quinoline formonitrile are quite important. It has an aromatic ring and a nitrile group, so it shows significant chemical activity.
The nitrile group is active and can be hydrolyzed to a carboxyl group. In acidic media, after a series of reactions, quinoline-2-carboxylic acid is finally formed. This reaction is like a clever conversion to obtain new organic compounds, which are widely used in the field of synthesis.
Nitrile groups can also be reduced to amine groups. Treated with suitable reducing agents, quinoline-2-methylamine can be obtained. Such nitrogen-containing compounds are crucial in the fields of medicine and materials chemistry, like the cornerstone of building complex structures.
The aromatic ring part, due to its electron cloud distribution characteristics, can undergo electrophilic substitution reactions. Reactions such as halogenation, nitrification, sulfonation, etc., can introduce functional groups at specific positions in the aromatic ring. For example, during halogenation, halogen atoms follow the electron cloud density and positioning rules of the aromatic ring, and replace hydrogen atoms at suitable positions to form halogenated quinoline derivatives, which provide the possibility for the subsequent synthesis of various compounds.
In addition, the conjugated structure of 2-quinoline formonitrile endows it with unique optical properties. In the field of photochemistry, it can be used as a fluorescent material. It is excited by light, electrons transition, and then emits fluorescence. It may be useful in detection, imaging and other technologies, just like a shimmer that lights up the road to exploration in the dark. Its chemical properties are diverse, opening doors to innovation in many fields, including organic synthesis, materials science, and pharmaceutical research and development.

2 + -Quinoline formonitrile has been synthesized in ancient times, and there are many methods.
First, it can be prepared from quinoline through a specific substitution reaction. Take the quinoline first, place it in a suitable reaction vessel, add a specific halogenating agent, such as a brominating agent or a chlorinating agent, and make it halogenate at a specific position in the quinoline ring under appropriate temperature and reaction conditions. Subsequently, add a cyanide reagent, such as potassium cyanide or sodium cyanide, and replace the halogen atom with a cyanide group through a nucleophilic substitution reaction to obtain 2 + -quinoline formonitrile. This process requires attention to the precise control of reaction conditions, such as temperature, reaction time and reagent dosage, to prevent side reactions from occurring.
Second, it is gradually converted by quinoline derivatives. First prepare quinoline derivatives containing specific functional groups, such as quinoline compounds with carboxyl or ester groups. Taking quinoline derivatives with carboxyl groups as an example, the carboxyl group can be converted into an acid chloride first, and reagents such as sulfoxide chloride are often used to react with it. Then the acid chloride is reacted with a cyanide reagent to obtain 2 + -quinoline formonitrile. This method requires multiple steps of reaction, each step needs to be carefully operated to ensure the smooth progress of the reaction, and it is also crucial for the purification and identification of intermediates.
Third, the reaction path of transition metal catalysis is adopted. Transition metal catalysts, such as palladium and copper, are used to catalyze the reaction of substrates containing quinoline structures with cyanide sources. In the reaction system, suitable ligands are added to enhance the activity and selectivity of the catalyst. Quinoline-containing substrates, cyanyl sources, transition metal catalysts and ligands are mixed in a certain proportion and reacted at a specific temperature and solvent conditions. This method has the advantages of relatively mild reaction conditions and high selectivity, but the catalyst cost is high, and its recovery and reuse need to be considered.
