N-[2-(trifluoromethyl)phenyl]-3,4-dihydroisoquinoline-2(1H)-carbothioamide

My question is about the chemical structure of "N- [2- (trifluoromethyl) phenyl] -3,4-dioxy isobenzofuran-2 (1H) -acetic anhydride". The structure of this compound is complex and needs to be analyzed according to the rules and knowledge of organic chemistry.
First view of the main body, "isobenzofuran" is the key skeleton. It has a unique cyclic structure and is formed by fusing the benzene ring with the furan ring. "3,4-dioxy" indicates that the introduction of oxygen atoms at the 3rd and 4th positions of isobenzofuran may have a significant impact on its chemical properties and reactivity. The electronegativity of oxygen atoms can cause changes in the distribution of electron clouds, making this area prone to reaction check points.
Furthermore, "2 (1H) " indicates that this compound has a hydrogen atom at the 2 position, and this hydrogen atom is in a specific chemical environment, or participates in many chemical reactions, such as nucleophilic substitution, redox, etc.
And the "acetic anhydride" structure is connected to the isobenzofuran skeleton. Acetic anhydride has an acyl structure and high chemical activity. It can participate in acylation reactions and react with nucleophilic reagents such as alcohols and amines to form esters or amides.
As for "[2- (trifluoromethyl) phenyl]", phenyl is a stable aromatic structure, while the introduction of trifluoromethyl significantly changes its electronic and spatial effects. Trifluoromethyl has strong electron absorption, which can reduce the electron cloud density of the benzene ring, which in turn affects the electron cloud distribution and reactivity of the skeleton connected to it. And its spatial hindrance is large, which may affect intermolecular interactions and reaction selectivity.
In summary, the chemical structure of "N- [2- (trifluoromethyl) phenyl] -3,4-dioxyisobenzofuran-2 (1H) -acetic anhydride" is composed of an isobenzofuran skeleton, dioxygen substitution, acetic anhydride, and trifluoromethyl-containing phenyl groups, and the interaction of each part endows the compound with unique chemical properties and reactivity.

The synthesis method of N- [2- (trifluoromethyl) phenyl] -3,4-dihydroisocoumarin-2 (1H) -lithium acetate relates to the field of organic synthesis. To obtain this compound, the common methods are as follows:
First, by using 2- (trifluoromethyl) benzoic acid as the starting material, it can be first converted into the corresponding acyl chloride, and then with o-hydroxyphenylacetic acid in the presence of a suitable base and catalyst, the key intermediate is formed. The precursor of the target compound can be prepared by the reaction of this intermediate through the inner ring of the molecule under specific conditions, such as heating, adding suitable dehydrating agent, etc. Finally, the precursor can be reacted with lithium reagents, such as n-butyl lithium, at low temperature and in an anhydrous and oxygen-free environment, N - [2 - (trifluoromethyl) phenyl] - 3,4 - dihydroisocoumarin - 2 (1H) - lithium acetate can be obtained.
Second, using o-hydroxybenzoic acid as the starting material, first reacts with halogenated alkanes, introduces corresponding substituents, and then undergoes a Ullman reaction or similar coupling reaction with halogenated aromatic hydrocarbons containing trifluoromethyl groups to construct a benzoic acid derivative with specific substituents. After that, through acylation, ring closure and other steps, it finally interacts with lithium reagents to achieve the synthesis of the target product.
Third, it can also start from 2 - (trifluoromethyl) benzaldehyde and react with ethyl o-hydroxybenzoate under alkali catalysis to generate unsaturated ester intermediates. This intermediate is finally reacted with lithium reagents through a series of operations such as reduction and cyclization to obtain the desired product.
All these methods have their own advantages and disadvantages. During synthesis, the appropriate synthesis path should be carefully selected according to many factors such as the availability of raw materials, the difficulty of controlling the reaction conditions, the yield, and the convenience of post-processing.

N- [2- (trifluoromethyl) phenyl] -3,4-dihydroisocoumarin-2 (1H) -cadmium acetate, this is an organic compound. Its physical properties are quite rich.
Looking at its morphology, it may be solid under normal conditions, because many organic compounds with similar structures are in a solid state. As for the color, or white to light yellow, due to the structure of these compounds, the degree of conjugation of aromatic rings and ester groups and the distribution of electron clouds make them absorb light differently. Common colors are mostly in this range.
When it comes to the melting point, in view of the presence of aromatic rings and ester groups in the molecule, the intermolecular forces are strong, so the melting point may be relatively high, and it is estimated that it is between 100 ° C and 200 ° C. Due to the rigid structure of the aromatic ring and the polarity of the ester group, the molecules are closely arranged, and high energy is required to destroy the lattice.
In terms of boiling point, due to the large molecular mass and the existence of various intermolecular forces, the boiling point may be between 300 ° C and 400 ° C to overcome the attractive forces between molecules and gasify. < Br >
In terms of solubility, since it is an organic compound and the molecular structure contains a hydrophobic aromatic ring part, it has little solubility in water; while in common organic solvents such as ethanol, ether, and dichloromethane, it may have a certain solubility. Due to the principle of similar miscibility, the intermolecular force between the organic solvent and the compound can promote dissolution.
The density may be slightly higher than that of water, because its molecular structure is compact and contains heavy atoms, resulting in an increase in unit volume mass.
In addition, the compound may have certain volatility, but due to the strong intermolecular force, the volatility is weak. And because the structure contains functional groups such as ester groups, it has characteristic absorption of infrared light of specific wavelengths, which can be characterized by infrared spectroscopy.
