摘要

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. 1H NMR, NICS, and an X-ray structural analysis of 1a reflect the aromatizing effect of double angular fusion on the central ring of the linear [3] phenylene substructure.
