5-Iodo-2-furaldehyde is an organic compound with unique chemical properties and important uses in many chemical reactions and fields.
This compound has an aldehyde group and a halogen atom, so it has the following characteristics. The aldehyde group gives it typical aldehyde chemical properties. First, oxidation reactions can occur. In case of weak oxidants such as Torun reagent (silver ammonia solution), a silver mirror reaction will occur. The aldehyde group is oxidized to a carboxyl group to give 5-iodo-2-furanoic acid. Strong oxidants such as potassium permanganate can also be oxidized, and the degree of oxidation may be deeper, and the product is more complex. Second, a reduction reaction can occur. For example, under the action of a suitable reducing agent such as sodium borohydride, the aldehyde group can be reduced to a hydroxyl group to obtain 5-iodo-2-furfuryl alcohol. Third, the aldehyde group can also participate in nucleophilic addition reactions, such as with alcohols under acid catalysis to form acetals.
Furthermore, the iodine atoms in the molecule also affect the reactivity of the compound. The iodine atoms are relatively large and have a certain electronegativity, which can reduce the electron cloud density of the benzene ring, which in turn affects the electrophilic substitution reaction activity on the benzene ring. Because the iodine atom is an ortho-para locator, the electrophilic reagents are easy to attack its ortho and para-sites. For example, when the electrophilic substitution reaction such as halogenation reaction and nitration reaction occurs, the substituent will mainly enter the ortho or para-position of the iodine atom.
In addition, 5-iodo-2-furaldehyde has a certain polarity due to the presence of iodine atom and aldehyde group, and has a certain solubility in organic solvents. Under certain conditions, intramolecular or intermolecular reactions may also occur, such as the formation of cyclic compounds, etc., depending on the reaction conditions and the ratio of reactants. In short, its chemical properties are determined by the aldehyde group and the iodine atom together, and have potential application value in the field of organic synthesis and other fields.

The synthesis method of 5-iodine-2-furanaldehyde has existed in ancient times, and there are many kinds. In the past, each family used its own capabilities to obtain this compound in different ways.
First, it can start from furan. First, the furan is combined with an appropriate halogenating agent, such as iodide and specific catalytic conditions, so that the iodine atom is attached to the fifth position of the furan ring. Then, in the step of introducing the aldehyde group, suitable oxidation means can be used, such as the selection of a specific mild oxidizing agent, so that the second position of the furan ring can be oxidized to obtain the aldehyde group, and finally 5-iodine-2-furanaldehyde.
Second, there are also other compounds containing furan structures as starting materials. If some of its existing functional groups are similar to the target, the technique of functional group transformation can be used. First, the existing functional groups are modified by ingenious methods, or protected or transformed, and then adjusted in sequence through a series of steps such as halogenation and oxidation to gradually approach the target structure, and finally the 5-iodine-2-furanal is obtained.
Third, there is still a way, which is to borrow the power of organometallic reagents. Combining the reagent containing furan fragments with the organometallic reagent, the unique activity of the metal reagent is used to guide the iodine atom to accurately access the 5-position, and then after subsequent processing, the aldehyde group is constructed at the 2-position. This method requires fine control of the reaction conditions, such as the choice of temperature and solvent, which are all crucial to success or failure.
All synthesis methods have their own advantages and disadvantages, or the steps are cumbersome, but the yield is considerable; or the conditions are harsh, but the selectivity is very good. To obtain this 5-iodine-2-furanal, it is necessary to weigh the advantages and disadvantages of various methods according to the specific situation, and choose the good one and follow it.
