Method for synthesis of sand smooth biphenyl

The invention discloses a synthetic method of 2-cyano-4'-methylbiphenyl, which adopts paratoluidine and benzoyl chloride as raw materials; a Friedel-Crafts acylation reaction is carried out under a Lewis acid catalysis condition; then a ring-closure reaction of a diazonium salt and a benzene ring is carried out in the presence of sodium nitrite; ring opening is carried out under an alkaline condition to generate a main product as shown in formula VI and a byproduct as shown in formula VII, and the ring-opening products are prepared into salts which are then subjected to separation; and finally, carboxyl groups are converted into cyan groups to obtain 2-cyano-4'-methylbiphenyl. The synthetic method of the invention has the advantages of easily available raw materials, safety, convenience for production management, low cost, reduction in 'three wastes' pollution, byproduct recyclability, and improved atom utilization rate.
