Summary:2-Acetylamino-2'-tellurocyanato-1,1'-binaphthyl (1) was prepared from the reaction of potassium tellurocyanate with 2-acetylamino-[1,1'- binaphthalene]-2'-diazonium chloride. Treatment of 1 with hydrochloric acid gave bis(2-amino-1,1'-binaphthalene-2'-yl) ditelluride (2) in 65% yield. Reaction of 2 with phenylacetyl chloride and trimethylacetyl chloride gave bis(2-phenylacetylamino-1,1'-binaphthalene-2'-yl) ditelluride (3) and bis(2-trimethyl-acetylamino-1,1'-binaphthalene-2'-yl) ditelluride (4), respectively. (2-Acetylamino-1,1'-binaphthyl-2'-yl)tellurium tribromide (5) was prepared by reaction of 1 with bromine. Partial reduction of 5 gave the corresponding tellurenyl bromide (6) which in turn reacted with KCN to afford compound 1 in good yield. Alkaline hydrolysis of 1 or reduction of 5 and 6 with hydrazine hydrate in boiling ethanol gave bis (2-acetylamino-1,1'-binaphthalene-2'-yl) ditelluride (7) in good yield. All these new compounds were characterized by elemental analyses, IR, 1H and 13C NMR and mass spectrometry.
