The interesting NMR spectral behavior of trisdehydro[4n+2]annuleno[4n1+2]annulenes (I,: n=n'=3 (1); Ib: n=n'=4 (2) and Ic: n=3, n'=4 (3)) inspired us to prepare a higher analogue of this series of annulenoannulenes, the trisdehydro-[18.10.2][14]annuleno[22]annulene (Id: n=3, n'=5) in order to get fu
