M. Sarobe et al., CYCLOPENT[FG]ACEPYRYLENE, CYCLOPENT[JK]ACEPYRYLENE AND CYCLOPENT[MN]ACEPYRYLENE - NOVEL C20H10 CYCLOPENTA-FUSED POLYCYCLIC AROMATIC-HYDROCARBONS, Journal of the Chemical Society, Chemical Communications, (23), 1995, pp. 2415-2416
Flash vacuum thermolysis of 1,8-(2a), 1,6-(2b) and 1,3-bis(1-chloroeth
enyl)pyrene (2c) gives the novel C20H10 cyclopenta-fused Polycyclic Ar
omatic Hydrocarbons (CP-PAHs) cyclopent[fg]- (1a), cyclopent[jk]- (1b)
and cyclopent[mn]acepyrylene (1c), respectively; bis(cyclopenta-fusio
n) topology has a profound influence on their properties.
