To prepare 2,3-cyclohexenone (5,6,7,8-tetrahydronaphthol), there are many methods, which are described in detail below.
One of them is the Diels-Alder reaction. This is a common magic method for constructing a six-membered cyclic structure. Using 1,3-butadiene and maleic anhydride as raw materials, under heating or lighting conditions, the corresponding bridge ring products can be obtained by [4 + 2] cycloaddition reaction. Subsequent steps such as hydrolysis and decarboxylation can obtain 2,3-cyclohexenone. The reaction process is as follows: 1,3-butadiene meets maleic anhydride, and molecular orbitals interact to form a new carbon-carbon bond, creating a bridged ring intermediate. Subsequent hydrolysis, the acid anhydride becomes diacid, and then through decarboxylation reaction, a molecule of carbon dioxide is removed, and the final product is obtained.
The second can be started from cyclohexanol. First, cyclohexanol is oxidized to cyclohexanone with an appropriate oxidizing agent, such as potassium dichromate acidic solution. Then cyclohexanone is eliminated by α-hydrogen under the action of strong bases, such as sodium amide (NaNH -2), to form a carbon-carbon double bond, thereby obtaining 2,3-cyclohexenone. In this process, the acidic solution of potassium dichromate oxidizes cyclohexanol hydroxyl to carbonyl, while the strong base captures α-hydrogen, promotes the elimination reaction, and builds the double bond structure in the target molecule.
Third, benzene can be considered as the starting material. Benzene is catalyzed to hydrogenate to cyclohexane, and cyclohexane is oxidized to cyclohexanol, which is then oxidized to cyclohexanone. After that, 2,3-cyclohexenone is synthesized through a reasonable design of enolization reaction and elimination reaction. During the enolization process, the α-hydrogen of cyclohexanone is removed by using an appropriate base to form enol negative ions, and then the double bond is constructed through the elimination step.
All these methods have their own advantages and disadvantages. The Diels-Alder reaction has relatively many steps, but the atomic economy is better; the cyclohexanol route is used as the raw material, and some step conditions are more harsh; the benzene route is used as the starting material, and the starting material is cheap and easy to obtain. However, the reaction steps are long, and the reaction conditions of each step need to be carefully planned to obtain 2,3-cyclohexenone efficiently.

In today's market, the price of 2,3-ethylene oxide (5,6,7,8-tetrahydrofuran) is difficult to determine. Its price varies due to changes in time, place, quality and supply and demand.
In the past, the production and use of this substance were not as prosperous as it is today, and its price was still flat. However, today is different from the past. Science and technology are advancing day by day, industry is booming, and many fields need this product, resulting in its prosperity. If there is a disaster in the place of origin or transportation obstruction, its production will decrease and supply will shrink, and the price will rise.
Looking at the present, if its quality is excellent, in the ordinary market, the price per catty may be around tens to hundreds of yuan. However, in block trade, or because of the huge purchase volume, the seller makes a profit, and the price may be discounted. And in remote places, due to the cost of transshipment, the price is higher than that of Tongdu Dayi. And the market is changing, and the competition among merchants is also fierce, either for profit or for market competition. It is difficult to predict the fluctuation of price.
In order to know the exact price, when you consult the merchants in the city, or look at the trading platforms, you can know the approximate price.
