| Summary: | Studies on the selective synthetic method for dialkyl ditellurides <b>1</b>, a representative class of organyl tellurium compounds, were presented. Considering the difficulty in conducting previous harsh reactions and in suppressing the formation of dialkyl tellurides <b>2</b> as side products, we optimized reaction conditions for selective syntheses of sodium ditelluride and the corresponding dialkyl ditellurides <b>1</b>. We reduced tellurium to sodium ditelluride by using NaBH<sub>4</sub> and subsequently, treated the obtained sodium ditelluride with alkyl halides (RX) to give the target compounds <b>1</b>. Consequently, by applying various alkyl halides (RX) we achieved the selective syntheses of dialkyl ditellurides <b>1</b> (13 examples with 4 new compounds) in modest to good yields. We also suggested the mechanistic pathways to dialkyl ditellurides <b>1</b>.
