| Abstrakt: | Two efficient syntheses of dibenzocyclooctadienediyne 1 were developed employing known reactions, which utilize commercially available reagents. Both methods are an improvement on known syntheses resulting in 41% and 43% overall yields. The latter method also offers an efficient synthesis of dibenzocyclooctatetraene 9, which is one of the key reagents now commercially unavailable. |
