ABSTRACT
2 - Oxo - 1,3 - bis (methoxy carbonyl) - 2 - H - cyclopenta [i]
acenaphthylene is prepared from base - catalyzed condensation of dimethyl
- 1,3 - acetone dicarboxylate with acenaphthenequlnone . 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 aprofic diazotization of 3,3' - dicarboxy -
4,4' - diaminobiphenyl is also trapped with this cyclone and leads to the
formation of tetra functional methyl carboxylate of bisbenzo [k] fluoranthene
derivative.
