✦ Synopsis

Tetrakisdehydro[14]annuleno[20]annulene consisting of an aromatic bisdehydro[14]annulene and an antiaromatic trisdehydro[20]annulene has been synthesized. The 'H NMR spectra clearly indicate the induction of para-and diamagnetic ring currents in each of the [4n]-and [4n+2]rings, respectively. Recently several kinds of [4n+2]annuleno[4n'+2]annulenes have been synthesized 1) affording
