Paragraph 0040; 0044, (2020/07/15)
The invention belongs to the field of organic chemical synthesis, and discloses a synthetic method of trans-4-alkyl cyclohexyl benzoic acid. According to the method, trans-4-alkyl cyclohexyl phenol isused as a raw material and reacts with sulfonyl chloride to generate aromatic sulfonate, a carbonyl insertion reaction of aromatic sulfonate is catalyzed by palladium to generate a trans-4-alkyl cyclohexyl benzoate compound with alkyl alcohol, and finally ester hydrolysis is performed to obtain the target product trans-4-alkyl cyclohexyl benzoic acid. The method has the advantages of mild reaction conditions, simple synthesis process, and high yield (up to 90% or above), the catalyst is safe and nontoxic and can be repeatedly used, and the synthesis method is environmentally friendly and canbe easily applied to industrial production.

A convenient method of obtaining 4-(trans-4 prime -n-alkylcyclohexyl) benzoic acids from alkanoyl chlorides, cyclohexane and benzene is described. Homologous series of above mentioned acids and their nitriles with alkyl tail 2 to 10 carbon atoms were prepared and temperatures of their phase transitions were determined.
