(This compound is 1 - (methoxy) -2,3 - dimethylnaphthalene, hereinafter referred to as this compound) Its chemical properties are as follows:
In this compound, the methoxy group has a donator effect, which will affect the electron cloud distribution of the naphthalene ring. There are lone pair electrons on the oxygen atom of the methoxy group, which can increase the electron cloud density of the adjacent and para-sites on the naphthalene ring through the conjugation effect, which in turn affects the electrophilic substitution activity of the compound. When the electrophilic substitution reaction occurs in this compound, due to the positioning effect of the methoxy group, the electrophilic reagents are more inclined to attack the adjacent and para-sites of the naphthalene ring connected to the methoxy group. The introduction of two methyl groups
also has an Methyl is an electron donor group, which can increase the electron cloud density of the naphthalene ring and improve the electrophilic reactivity of the compound. Moreover, the steric hindrance effect of methyl cannot be ignored. In some reactions, the steric hindrance will hinder the proximity of the reagent to the specific position of the molecule, affecting the selectivity and rate of the reaction.

What is the preparation method of 1- (chloromethyl) -2,3-dimethylbenzene?
To prepare 1- (cyanomethyl) -2,3-dimethylpyridine, you can follow the following ancient methods.
First take an appropriate amount of pyridine and place it in a clean reactor. Pyridine is the basic raw material for this synthesis, and its properties are stable. When encountering appropriate reagents and conditions, it can start the reaction.
Prepare cyanide reagents, such as potassium cyanide or sodium cyanide, dissolve in a suitable solvent and slowly drop into the reactor containing pyridine. The cyanide group of the cyanide reagent will undergo nucleophilic substitution reaction with the specific position of the pyridine. This is the key step in introducing cyanomethyl. When adding dropwise, the rate and temperature must be strictly controlled to prevent overreaction. The temperature should be maintained in the low temperature range, such as 0-5 ° C. This temperature range can make the reaction proceed smoothly and reduce the occurrence of side reactions.
After the cyanidation step is completed, the intermediate product containing cyanomethyl pyridine is obtained. Then, proceed to introduce dimethyl. Select a suitable methylation reagent, such as iodomethane or dimethyl sulfate, etc. The methylation reagent is slowly added to the above reaction system under alkaline conditions. The alkaline environment can activate the pyridine ring, so that the methylation reaction is prone to occur.
During the reaction process, the reaction progress can be closely monitored by thin-layer chromatography or other analytical methods. When the reaction reaches the expected level, the reaction is terminated. After the reaction mixture is post-treated, the product is extracted with an organic solvent to separate the impurities. Commonly used organic solvents such as ether, dichloromethane, etc., the product can be dissolved in such solvents.
After extraction, the organic phase is washed to remove residual reagents and impurities. Wash successively with water, dilute acid, and dilute alkali solutions. After each step of washing, let stand and stratify, and discard the aqueous phase.
Finally, the organic phase is dried. A desiccant such as anhydrous sodium sulfate or magnesium sulfate can be used to absorb the moisture. After drying, the desiccant is filtered off, and the filtrate is distilled under reduced pressure to collect a fraction with a specific boiling point range, which is the product of 1- (cyanomethyl) -2,3-dimethylpyridine. The whole process requires fine operation to control the conditions of each link in order to obtain a pure product.
