Abstract: | Treatment of the di-lithium derivative of 1,2-diethynyl-benzene () with -xylene-α,α′-diol di--toluenesulphonate () in tetrahydrofuran led to 5,12-dihydronapthacene () as the only identifiable product. This reaction presumably involves 5,12-dihydro-6,11-didehydronaphthacene () as an intermediate, and this was confirmed by the formation of 5,12-dihydro-6,11-dideuterio-naphthacene when the reaction was carried out in tetrahydrofuran-8. |
