    • According to an examination carried out by our group, di-tert-butyl disulfide does not serve as an effective sulfurizing agent without UV irradiation.

    • TEST is commercially available from Gelest and Shin-etsu, Tokyo, Japan. This liquid reagent is freely soluble in various organic solvents including toluene, tetrahydrofuran, acetonitrile, and N-methylimidazole at ambient temperature.

    • N-Methyl-2-pyrrolidone and HMPA are rather expensive, and HMPA is highly toxic. tert-Butyl alcohol, the melting point of which is ca. 26°C, runs the risk of freezing in the delivery tubes of the synthesizer.

    • In the solid-phase synthesis of a dinucleoside phosphorothioate, 5 min of sulfurization suffices to obtain a high yield of the product. In contrast, for the synthesis of this size of oligomers, i.e. dimers, more time (at least 10 min) is required for sulfurization in order to obtain a satisfactory yield of the target product.

    • According to recent catalogs, the respective prices of TEST and the Beaucage reagent are as follows: TEST costs $280/mol (Gelest), $400/mol (Shin-etsu), $2,500/mol (Fulka), and the Beaucage reagent costs $26,800/mol (Aldrich).
