Nucleophilic addition of a divalent silicon species bearing the 8-dimethylamino-1-naphthyl group to diphenylacetylenes to form the 1-amino-1-silaphenalene skeleton

A 1-amino-1-silaphenalene skeleton is formed by the reaction of a divalent silicon species bearing the 8-(dimethylamino)-1-naphthyl group with diphenylacetylene via an alkenyl anion intermediate.
