The invention discloses a compound and a preparation method and application thereof. The compound has a formula 1 which is shown in the description, wherein R1 to R6 are independently and respectively selected from alkyls with the total number of hydrogen or carbon atoms of 1-3, and R7 is selected from alkyls or halogens with the total number of hydrogen or carbon atoms of 1-3. Through the adoption of a catalyst combination with the compound as a main catalyst, acetylene can be catalyzed to have a cyclotrimerization reaction to generate benzene, and in the reaction, the conversion rate of acetylene and the selectivity of benzene are higher, the service life of the catalyst can keep long, and therefore the compound is suitable for the industrialized scale-up production of benzene generated by the cyclotrimerization reaction of acetylene and has very good market application prospects. 本发明公开了种化合物及其制备方法和应用，所述化合物为式1所示化合物；其中，R至R分别独立地为选自氢或碳原子总数为1-3的烷基，R为选自氢、碳原子总数为1-3的烷基或卤素。采用该化合物作为主催化剂组成的催化剂组合物可以催化乙炔发生环三聚反应生成苯，且反应中乙
