| Abstract: | Bisdehydro14]- and 18]annulenediones have been synthesized by cyclic dimerization of corresponding -ethynyl acid chlorides in the presence of palladium-copper catalyst in triethylamine-benzene and fully characterized by analyses and their 1H-NMR, mass, electronic and IR spectroscopic evidences. |
