Abstract

Our studies have now been extended to acetylenic hydrocarbons, which were found to cyclotrimerize and to cyclocodimerize with conjugated dienes by the action of Fe (COT) 2. 2- Butyne and diphenylacetylene (tolane) were cbyclotrimerized to hexamethylbenzene and to hexaphenylbenzene, respectively. Both acetylenic compounds were cyclocodimerized with 1, 3-butadiene to 1, 2-disubstituted 1, 4-cyclohexadienes. In this note we also report the ...
