There are many different methods for synthesizing 3-iodobenzoyl chloride. Here are a few common ones.
First, 3-iodobenzoic acid is used as the starting material. First, 3-iodobenzoic acid is heated with thionyl chloride to undergo an acylation reaction to obtain 3-iodobenzoyl chloride. This step requires a suitable temperature, usually near the boiling point of thionyl chloride, when heated for a number of refluxes, to promote the complete reaction. Then, the obtained 3-iodobenzoyl chloride and excess ammonia are slowly reacted at a low temperature, such as between 0 ° C and 5 ° C, to obtain 3-iodobenzoamide. Finally, with a strong reducing agent such as lithium aluminum hydride, 3-iodobenzamide can be obtained by heating and refluxing in an organic solvent such as anhydrous ether or tetrahydrofuran to reduce 3-iodobenzamide. In this process, the ratio of lithium aluminum hydride to the substrate needs to be precisely controlled, and the post-reaction treatment needs to be handled with caution to prevent danger.
Second, 3-iodobromobenzene is used as the starting material. First, 3-iodobromobenzene is reacted with magnesium chips in anhydrous ether to form Grignard's reagent 3-iodophenyl magnesium bromide. This reaction needs to be carried out in an anhydrous and anaerobic environment to prevent the decomposition of Grignard's reagent. Next, 3-iodobenzyl magnesium bromide is reacted with formaldehyde solution at low temperature to generate 3-iodobenzyl alcohol. Subsequently, 3-iodobenzyl alcohol is reacted with dichlorosulfoxide to convert into 3-iodobenzyl chloride. Finally, 3-iodobenzyl chloride is reacted with ammonia or aminating reagents to obtain 3-iodoaniline. Although there are many steps in this route, the reaction conditions of each step are relatively mild and easy to control.
Third, 3-nitrobenzyl amine is used as raw material. First, iodine substitution reagents, such as iodine and copper powder, under specific conditions, 3-nitrobenzamine is iodized to obtain 3-iodine-nitrobenzamine. Then, the nitro group is reduced with reducing agents such as iron and hydrochloric acid to obtain 3-iodoaniline. This method requires attention to the selectivity of the iodine substitution reaction and the regulation of the reaction conditions during the reduction process to prevent excessive reduction or other side reactions.

3-iodobenzenemethanamine, that is, 3-iodoaniline, there are many things to pay attention to when storing and using this substance.
When storing, the first choice of environment. Because of its nature or instability, it should be placed in a cool, dry and well-ventilated place. If the environment is humid, water vapor is easy to interact with it, or cause deterioration; if the temperature is too high, it may also cause chemical reactions, so it is necessary to be cool and dry. And it needs to be kept away from fires and heat sources to prevent it from being dangerous when heated. Furthermore, it should be stored separately from oxidants, acids, etc. Because of its active chemical properties, contact with these substances, or react violently, causing safety accidents.
When using, protective measures are indispensable. Appropriate protective clothing, gloves and goggles should be worn, as it may be irritating to the skin and eyes, and direct contact can cause damage. The operation should be carried out in a fume hood to prevent its volatile gaseous substances from accumulating in the air. If inhaled into the body, it may endanger health. During use, strictly follow the operating procedures, precisely control the dosage, avoid waste, and prevent uncontrollable reactions caused by excessive use. After use, properly dispose of the remaining substances and waste, do not discard them at will, and dispose of them in accordance with relevant regulations to prevent environmental pollution.
In short, the storage and use of 3-iodobenzenemethanamine should be treated with caution, paying attention to the environment, protection and operating standards to ensure safety and avoid adverse consequences.
