Abstract:Synthesis of naphtho-tri-t-butyltrisdehydro16]annulene containing a hexapentaene and an acetylene units has been described. It was found that the 16]annulene is less stable and the paratropicity is much stronger as compared with previously reported isomeric naphtho16]-annulene containing a diacetylene and a butatriene linkage.
