Abstract

Abstract: Interaction of 9, lO-dihydroanthracene and its 9-and 10-methyl and ethyl derivatives (la-f) with n-butyllithium in cyclohexane and excess N, N, N', N '- tetramethylethylenediamine afforded the respective dianionic intermediates. The latter on treatment with cadmium (I1) chloride or other metal salts underwent transformation to fully aromatic hydrocarbons in essentially quantitative yield. The presence of a secondary or ...
