To prepare benzo [b] thiophene-3-formonitrile, there are various methods. First, starting with o-bromothiophenol and acrylonitrile, through alkali catalyst, nucleophilic addition, to obtain an intermediate, and then cyclized to form benzo [b] thiophene-3-formonitrile. This way is simple, but the raw materials may not be easy to obtain.
Another method, using benzo [b] thiophene as the base, brominated to obtain 3-bromobenzo [b] thiophene, and then cyanide with cuprous cyanide in high temperature and high boiling solvent cyanide reaction. This process requires strict control conditions, and cuprous cyanide is highly toxic, so use caution.
There are also 2-acetylbenzo [b] thiophene as raw material, which can be prepared by oximization to obtain 2-acetylbenzo [b] thiophene oxime, and then dehydration. The raw material of this route is easy to obtain, but the steps are slightly complicated, and it needs to be purified in multiple steps.
Another thiopheno [2,3-b] pyridine is used as raw material, and a series of reactions such as oxidation and denitrification are carried out to obtain benzo [b] thiophene-3-formonitrile. This route is novel, but the reaction is complex, requiring professional skills and equipment.
Each method has advantages and disadvantages. When choosing a method, it depends on various factors such as the availability of raw materials, the difficulty of operation, the level of cost, and the amount of yield.

Wen Jun inquired about the market price of benzo [b] thiophene-3-formonitrile. This is a rather specialized chemical in the field of fine chemicals. Its market price often changes due to multiple factors, making it difficult to give you an exact price.
First, the impact of the production source is crucial. The abundance of raw materials and the rise and fall of prices have a great impact on their cost and selling price. If the supply of specific sulfur sources and benzene series raw materials required for the production of benzo [b] thiophene-3-formonitrile is tight, or the price rises due to market fluctuations, the production cost will rise, which will in turn drive up the price of the product.
Second, the ups and downs of market demand also affect its price. If there is a strong demand for this chemical in the fields of pharmaceutical research and development, new material preparation, etc., and the supply is in short supply, its price will rise; on the contrary, if the demand is sluggish and overcapacity, the price will have downward pressure.
Third, the difference in production process is also related to cost and price. Advanced and efficient processes can reduce costs. If enterprises can produce at low cost and high output, they may gain an advantage in market pricing and compete at relatively low prices. Those with backward and inefficient processes have high costs and difficult prices.
Fourth, the market competition situation has far-reaching implications. If there are many market participants and the competition is fierce, and each manufacturer is competing for a share, it may attract customers with price strategies, resulting in lower prices. If the market is almost monopolized and there are only a few suppliers, its pricing power will be enhanced, and prices may be relatively high.
In addition, regional differences, transportation costs, policies and regulations, etc., may also make prices different in different regions and time periods. To know the exact market price, you can consult the chemical product trading platform, relevant distributors, or communicate directly with the manufacturer to obtain the latest and accurate price information.

Benzo [b] thiophene-3-formonitrile must be remembered when using it. This is an important chemical with unique properties and should not be used carelessly.
First, it is related to safety protection. Benzo [b] thiophene-3-formonitrile may be toxic and irritating. When in contact, you must wear appropriate protective equipment. Protective clothing can prevent it from contacting the skin and prevent skin damage; protective gloves must be selected to prevent poisons from entering the body through gaps; goggles are also indispensable to protect the eyes from damage. The place where the operation is located must be well ventilated. If the ventilation is not smooth, the volatile gas will gather in one place and be inhaled into the body, which is very dangerous.
Second, there is also attention to access and storage. When taking it, the appliance must be clean and dry to avoid impurities mixed in and cause its properties to change. When measuring, when precise operation, according to the required amount, not less than a millimeter. Store in a cool, dry and ventilated place. Keep away from fire and heat sources. This chemical may be flammable and dangerous in case of open flames and hot topics. And it should be separated from oxidants, acids, alkalis, etc. to prevent mutual reaction and cause accidents.
Third, the operation process must be rigorous. When used in chemical reactions, reaction conditions such as temperature, pressure, reaction time, etc., should be strictly controlled. If the temperature is too high or too low, or the reaction rate is abnormal, the product is impure; if the pressure is uncomfortable, or the reaction process is affected. Improper reaction time, or the reaction does not meet expectations, or excessive reaction, wasting raw materials. When operating, pay close attention to the reaction phenomenon. If there is any abnormality, stop the operation immediately to find out the reason, and ensure the effectiveness of the experiment.
