ABSTRACT:
A composition suitable for sulfurizing an organophosphite. The reagent comprises a solution of sulfur and a non-aromatic tertiary amine, in a suitable solvent such as carbon disulfide. The non-aromatic tertiary amine is preferably an optionally substituted trialkyl amine, for example triethylamine or diisopropylethylamine. A method is also provided in which phosphites or phosphonates are sulfurized to their corresponding phosphorothioates or phosphonothioates, respectively, using compositions of the present invention. This method has particular application to produce internucleotide phosphorothioate or phosphonothioate bonds in a nucleotide multimer.
