There is currently a synthesis of (trans-4-pentylcyclohexyl) -4-cyanobenzene. The method is as follows:
First, the appropriate starting material is taken, and cyclohexanone is used as the base. After a multi-step reaction, trans-4-pentylcyclohexanol is prepared. Shilling cyclohexanone and amyl halide are catalyzed by a strong base, and nucleophilic substitution is carried out to introduce amyl groups to obtain 4-pentylcyclohexanone. This step requires mild reaction conditions to avoid side reactions and affect the yield. Then, 4-pentylcyclohexanone is reduced to 4-pentylcyclohexanol with a suitable reducing agent, such as sodium borohydride. The reaction is carried out in an alcohol solvent, and the temperature should be controlled in a moderate range, so that the reaction occurs smoothly.
After dehydration, 4-pentylcyclohexanol is converted into 4-pentylcyclohexene. Often strong acids such as sulfuric acid or p-toluenesulfonic acid are used as catalysts, and heating is used to dehydrate the alcohol to alkenes. This step should pay attention to the reaction temperature and time to prevent side reactions such as overreaction or polymerization. After 4-pentylcyclohexene is obtained, it is halogenated and added to the double bond with bromine or chlorine in a suitable solvent, such as carbon tetrachloride, to obtain 4-pentyl-1,2-dihalocyclohexane.
Then, the elimination reaction is performed, and 4-pentyl-1,2-dihalocyclohexane is treated with an alcohol solution of a strong base such as potassium hydroxide to obtain trans-4-pentylcyclohexene. This step aims to construct the trans structure, which is crucial for the precise control of the reaction conditions.
In addition, cyanobenzene is used as a raw material, and the coupling reaction with trans-4-pentylcyclohexene occurs under appropriate reaction conditions. Transition metal catalysis methods, such as palladium-catalyzed cross-coupling reactions, can be used to form (trans-4-pentylcyclohexyl) -4-cyanobenzene. Appropriate ligands need to be added to the reaction system to enhance the activity and selectivity of the catalyst. At the same time, the reaction temperature, time and proportion of reactants are carefully regulated, so that the reaction proceeds in the direction of generating the target product, and finally (trans-4-pentylcyclohexyl) -4-cyanobenzene can be obtained. After each step of the reaction, the product needs to be purified by suitable separation and purification methods, such as distillation, recrystallization, column chromatography, etc., to ensure the purity of the raw materials in the next step of the reaction and improve the efficiency and product quality of the overall synthesis.

(Trans-4-benzylcyclohexyl) - 4-nitrile This substance has many precautions during storage and transportation.
