Tetrachloro-1, 4-benzoquinone and 2, 3-dichloro-1, 4-naphthoquinone react with a variety of aryl or alkyl tellurolate, generated either by the reaction of Grignard reagents and tellurium powder or by the reduction of ditelluride with sodium borohydride, to give 2, 5-diaryl (alkyl) telluro-3, 6-dichloro-1, 4-benzoquinones and 2, 3-diaryl (alkyl) telluro-1, 4-naphthoquinones is good yields.

Key words: NAPHTHOQUINONE, GRIGNARD REAGENT, NUCLEOPHILIC REAGENTS, BENZOQUINONE, TELLURIUM, CHEMICAL REACTION
