ABSTRACT
[24]Pentaphyrin(2.1.1.1.1) 1 was synthesized by dehydrogenation of dihydropentaphyrin(2.1.1.1.1) 2 as the first example of vinylogous pentaphyrin. Pentaphyrin 1 takes a roughly planar structure and shows strong antiaromatic character, reflecting a 24π-conjugated circuit. In spite of the antiaromatic character and the relatively small circuit, 1 is stable under ambient conditions.
