The invention relates to a method for preparing polyaromatic substituted naphthalene derivatives through the cyclization reaction of aromatic ketones and tolanylacetylene catalyzed by ruthenium and its application. The present invention uses relatively cheap ruthenium as a catalyst to activate the aromatic ketone β-H to synthesize a six-membered ring to generate polyaromatic substituted naphthalene derivatives; no additives and oxidants are required during the reaction, and only a simple base is used, and the reaction is carried out under mild reaction conditions . The synthesis method provided by the invention is simple, feasible, scientific and reasonable, environmentally friendly, economical and practical, and suitable for large-scale production. |
