Abstract :
2 - Oxo - 1,3 - bis (methoxy carbony) - 2- H- cyclopenta [i] acenaphthylene is prepared from base - catalyzed condensation of dimethyl - 1,3 - acetone dicarboxylate with acenaphthenequinone. Benzyne generated from anthranilic acid is trapped with this cyclone and 7,12 - dimethyl carboxylate benzo [K] fluoranthene as a new monomer is obtained in quantitative yield. Bisbenzyne from aprotic diazotization of 3,3 - dicarboxy - 4,4 - diaminobipheny is also trapped with cyclone and leads to the formation of tetra functional methyl carboxylate of bisbenzo [K] fluoranthene derivative.
