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

A bisdehydro[l4]annuleno[c]furan, an isoannelated diatropic annulene, has been synthesized. Cyclic glycol, a precursor of the annuleno[c]furan, could be converted into bisdehydro[l4]annulene derivatives under mild acidic conditions. We have already prepared a series of annelated [4n+2]annulenes fuse
In the previous paper (1) we have described a two-step synthesis of 1,6-methanaCl0lannulen-1 l-one from tropone. This compound, having the p-orbital of the carbonyl group .approximately perpendicular to the peripheral IOn-electron system, failed to exhibit appreciable n-n interaction between them. W
