【発明の名称】有機リン化合物をイオウ化するための方法およびそのための試薬
Document Type and Number:
Japanese Patent JP2898750
Kind Code:
B2
Abstract:
A composition suitable for sulfurizing an organophosphite comprises a solution of sulfur and a tertiary amine, in a suitable solvent such as carbon disulfide. The tertiary amine is preferably an optionally substituted trialkyl amine, for example triethylamine or diisopropylethylamine. Phosphites or phosphonous esters may be sulfurized to their corresponding phosphorothioates or phosphonothioates, respectively, using these compositions and this is particularly useful in producing internucleotide phosphorothioate or phosphonothioate in a nucleotide multimer.
