Synthesis method of 4-alkyl biphenylacetylene

The invention discloses a synthesis method of 4-alkyl biphenyl acetylene. The synthesis method comprises the following steps: carrying out catalytic hydrogenation reaction on 4-alkyl diketone to obtain 4-alkyl biphenyl; then reacting the 4-alkyl biphenyl with halogen to obtain 4-halogen-4 '-alkyl biphenyl; and allowing 4-halo-4 '-alkyl biphenyl and an ethynylation reagent to be subjected to a coupling reaction to obtain a compound shown in a formula (IV) under the action of alkali. The method creatively adopts a palladium catalyst and lewis acid combined catalytic system to carry out deoxidation reaction on 4-alkyl diketone, and has good selectivity and high yield; in addition, hydrogen is used as a hydrogen source, a byproduct is only water, and the method is environment-friendly.
