摘要

The reaction of 8 -dimethylamino-l-naphthyllithium diethyl etherate with tellurium powder and subsequent O-2 oxidation was reinvestigated. Besides the previously reported bis[8-(dimethylamino)naphthyl] ditelluride (1), the new bis[8-(dimethylamino)naphthyl] tritelluride (2) was isolated in 42% yield and fully characterized. Low-temperature Te-125 NMR spectroscopy provides evidence to suggest that analytically pure 2 is in equilibrium with 1 and bis[8-(dimethylamino)-naphthyl] tetratelluriae (2a).
