In-depth understanding of it is the basis for giving full play to its properties and uses.
Is the chemical properties of 2,7-diiodine-9,9-dimethylfluorene stable?
The chemical properties of 2% 2C7-dinaphthalene-9% 2C9-dimethylbenzyl alcohol are quite stable. In its structure, the naphthalene group interacts with the dimethylbenzyl alcohol group to form a relatively stable structure.
From the perspective of intermolecular forces, the conjugated system of naphthalene group provides a large electron delocalization range and enhances the stability of the molecule. At the same time, the methyl group of the dimethylbenzyl alcohol part has a electron donor effect, which can stabilize the positive charge center in the benzyl alcohol structure and reduce the reactivity check point.
Furthermore, the C-C bond and C-H bond energy in such compounds are quite high, and high energy is required from the outside world to break the chemical bond. Under common conditions, it is not easy to chemically react with most reagents. In the case of general oxidizing agents and reducing agents, it is difficult to initiate a reaction without special conditions.
However, although its chemical properties are stable, it can still exhibit reactivity under specific conditions, such as high temperature, strong acid-base environment or the presence of specific catalysts. For example, under the catalysis of concentrated sulfuric acid, dehydration reactions may occur; in the case of strong oxidizing agents, under high temperature and high pressure, the naphthalene ring or the benzyl alcohol part may be oxidized. In general, the chemical properties of 2% 2C7-dinaphthalene-9% 2C9-dimethylbenzyl alcohol are stable under normal and mild conditions.
What are the synthesis methods of 2,7-diiodine-9,9-dimethylfluorene?
The synthesis method of 2% 2C7-dinaphthalene-9% 2C9-dimethylbenzyl alcohol has been known for a long time, and each method has its own wonders. Today, let's describe its common methods for you.
First, based on naphthalene, halogenated naphthalene is obtained by halogenation. Then it is co-placed in an ether with magnesium chips to form a Grignard reagent. Complex with dimethyl formaldehyde and encounter it, through reaction and hydrolysis, the alcohol can be obtained. The key to the method, the accuracy of halogenation, the proper preparation of Grignard reagents, and the moderation of hydrolysis are all about success or failure.
Second, also starting with naphthalene, by acylation, naphthalene acetonoids are obtained. After using sodium borohydride or lithium aluminum hydride as the reducing agent, in an appropriate solvent, the carbonyl group is converted into a hydroxyl group, and the alcohol can also be formed. The key here is to control the acylation conditions, the trade-off of the amount of reducing agent, and the choice of solvent, which are all factors that affect the yield and purity.
Third, you can start from dichexol, introduce dimethyl benzyl through alkylation, and then reduce it to make the hydroxyl group configuration appropriate, and finally obtain this alcohol. In the alkylation step, you need to choose a good agent, control the temperature, control it, and pay attention to the conditions when reducing, so that the product can be combined with the desired.
All these methods have their own advantages and disadvantages. Or the raw materials are easily available and the steps are cumbersome, or the conditions are harsh and the yield is quite high. To obtain the best method, it must be determined according to the availability of raw materials, the level of cost, and the difficulty of the process.
