The invention discloses a compound and a method for preparing benzene by performing trimerization on acetylene. The compound is a compound shown as a formula I in the description, wherein R to R are independently selected from alkyl groups containing hydrogen or carbon atoms with the total amount of 1 to 3; R to R are independently selected from the alkyl groups or halogen containing hydrogen and carbon atoms with the total amount of 1 to 3; R is the alkyl group containing hydrogen or carbon atoms with the total amount of 1 to 3. A catalyst composition prepared from the compound serving as a main catalyst can be used for catalyzing cyclotrimerization of the acetylene to generate the benzene, relatively high conversion rate of the acetylene and relatively high selectivity of benzene are achieved in the reaction, the service life of the catalyst can last a relatively long time, so that the catalyst is suitable for industrial amplification production in which the acetylene is subjected to the cyclotrimerization
