1 - (hydroxymethyl) -4- (trifluoromethoxy) benzene, the physical properties are as follows:
It is an organic compound, mostly in liquid or solid state at room temperature, and the specific phase state is affected by factors such as intermolecular forces. Looking at its appearance, it is usually a colorless to light yellow transparent liquid or white solid powder. Due to differences in preparation process and purity, the appearance may be different.
The boiling point of 1 - (hydroxymethyl) -4- (trifluoromethoxy) benzene is determined by molecular structure and relative molecular mass. There are van der Waals forces and hydrogen bonds between molecules, so that its boiling point is in a specific range. The exact value needs to be determined experimentally.
Its melting point depends on the regularity of molecular arrangement and lattice energy. The molecular action force in the lattice is strong, and the melting point has a certain height. Accurate melting point data can be obtained by experimental determination.
The solubility of this substance is related to molecular polarity. It contains hydroxymethyl, has a certain polarity, and has better solubility in polar organic solvents such as ethanol and acetone. The existence of trifluoromethoxy group makes it have a certain solubility in some non-polar solvents.
1- (hydroxymethyl) -4- (trifluoromethoxy) The density of benzene is affected by the degree of molecular packing compactness and relative molecular weight. The relative molecular weight is large, the molecular arrangement is close, and the density is relatively high. It can be accurately measured by experiments.
From the stability point of view, it is stable under general conditions, but it encounters strong oxidants, strong acids, strong bases, etc., or changes due to chemical reactivity. Because it contains active hydroxymethyl groups, it can participate in esterification, oxidation and other reactions; trifluoromethoxy groups affect the distribution of molecular electron clouds and change the reactivity and selectivity.

1 - (benzyl) -4 - (trifluoromethoxy) benzene, the chemical properties of this substance are quite stable. Looking at its structure, benzyl is also benzyl, which is connected to the benzene ring, giving the molecule a certain steric hindrance and electronic effect. And trifluoromethoxy, due to the strong electronegativity of fluorine atoms, gives the group electron-absorbing properties, which affects the electron cloud distribution of the whole molecule.
In terms of reactivity, due to the existence of the conjugate system of the benzene ring, the molecule is relatively stable. Although benzyl can participate in some reactions such as nucleophilic substitution, specific reaction conditions are required. The presence of trifluoromethoxy reduces the electron cloud density of the benzene ring to a certain extent, making the electrophilic substitution reaction more difficult to occur than benzene itself, requiring stronger electrophilic reagents and more severe reaction conditions.
In common chemical reaction environments, if there is no specific catalyst, suitable temperature and pressure to change its reactivity, this compound can maintain a relatively stable state. For example, at room temperature and in general solvent environments, there are few spontaneous significant chemical reactions. Its stability comes from the balance of interactions between groups in the structure, the conjugation of the benzene ring, the electronic effects and space effects of benzyl and trifluoromethoxy, which together build a relatively stable chemical structure.

To prepare 1 - (hydroxymethyl) -4 - (trifluoromethoxy) benzene, there are three methods.
First, p-trifluoromethoxy benzaldehyde is used as the beginning, and through the co-reaction with formaldehyde and alkali, according to the principle of hydroxyaldehyde condensation, the intermediate product can be obtained. After reduction, if treated with a reducing agent such as sodium borohydride, it can become the target 1 - (hydroxymethyl) -4 - (trifluoromethoxy) benzene. This way, the starting material is easy to find, and the reaction steps are relatively simple. However, the control of hydroxyaldehyde condensation needs to be fine to avoid side reactions.
Second, starting from p-trifluoromethoxy bromobenzene, first make Grignard reagent, and then react with formaldehyde or paraformaldehyde to form alcohol. When making Grignard reagent, the reaction conditions must be strict, anhydrous and oxygen-free, otherwise Grignard reagent is easy to decompose and cause the reaction to fail. However, the atomic economy of this way is acceptable, if the operation is appropriate, the yield can also be observed.
Third, take p-trifluoromethoxy benzoic acid as raw material, first esterify it to obtain the corresponding ester, and then reduce it with a strong reducing agent such as lithium aluminum hydride, and the target product can be obtained. In this process, the esterification reaction is easier, but the use of lithium aluminum hydride must be careful, because it is active and easy to explode in contact with water. However, its reducing power is strong, and ester groups can be efficiently converted into hydroxymethyl groups.
All these ways have their own advantages and disadvantages. Experimenters should choose their methods carefully and carefully according to the requirements of raw materials, equipment and products. Only then can they obtain satisfactory results.
