What are the chemical properties of (2Z) -6,6 '-dichloro-4,4' -dimethyl-3H, 3'H-2,2 '-bi-1-benzothiophene-3,3' -dione?

(2Z) -6,6 '-difluoro-4,4' -dimethyl-3H, 3'H-2,2 '-di-1-naphthothiazole-3,3' -dione, which has the following chemical properties:
Its molecules contain fluorine atoms, methyl, thiazole rings, naphthalene rings and dione structures, which endow it with diverse chemical properties.
From the perspective of electronic effects, fluorine atoms are highly electronegative and have strong electron-absorbing induction effects, which can change the density distribution of molecular electron clouds. It can affect the polarity of surrounding chemical bonds, reduce the density of electron clouds connected to carbon atoms, enhance their electrophilicity, and facilitate the attack of nucleophiles. Under suitable conditions, nucleophilic reagents such as alcohols and amines can undergo nucleophilic substitution reactions with fluorocarbon atoms.
methyl is a power supply group, which provides electrons to connected atoms through superconjugation effect, which can increase the electron cloud density of connected carbon atoms and reduce their electrophilicity to a certain extent, which is the opposite of fluorine atoms. However, methyl groups have small steric resistance and limited influence on molecular spatial structure, but they will have subtle effects on reaction activity and selectivity.
thiazole ring is a five-membered heterocycle containing sulfur and nitrogen, which has aromatic properties. Its nitrogen and sulfur atoms have lone pair electrons, which can participate in coordination and form complexes with metal ions. The ring has high stability and can participate in some heterocyclic-specific reactions, such as electrophilic substitution reaction with electrophilic reagents under specific conditions, and the reaction check point is mostly at the position of higher electron cloud density. The
naphthalene ring, as a fused ring aromatic hydrocarbon, also has aromatic properties, and can undergo electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. The electron cloud density distribution of the naphthalene ring is uneven. The electron cloud density of the α position is higher than that of the β position, and the electrophilic substitution reaction preferentially occurs at the α position. In the
diketone structure, the carbonyl group has strong polarity, and the carbon atom in the carbon-oxygen double bond is positively charged, which is vulnerable to the attack A variety of reactions can occur, such as the formation of ketals with alcohols catalyzed by acids to protect carbonyl groups; and the condensation reaction with ammonia and its derivatives to form nitrogen-containing heterocyclic compounds. Under basic conditions, diketones can undergo intramolecular or intermolecular condensation reactions to build more complex cyclic structures.

Furthermore, when designing the reaction route, the mildness of the reaction conditions, the yield and the difficulty of post-treatment should be considered. Mild reaction conditions help to reduce the restrictions on substrates, improve the selectivity and operability of the reaction; high yield can improve the synthesis efficiency and reduce the cost; simple post-treatment is conducive to the purification and separation of the product, and obtain a high-purity target product.
