摘要：

[GRAPHICS] The parent and dipropyl-substituted anti (1a,b) and syn doublebent (2a,b) [5]phenylenes have been assembled by CpCo-catalyzed double cyclization of regiospecifically constructed appropriate hexaynes. H-1 NMR, NICS, and an X-ray structural analysis of is reflect the aromatizing effect of double angular fusion on the central ring of the linear [3]phenylene substructure.
