Abstract The opening of the S8 ring with the formation of linear sulfur oligomers in the presence of tri-n-butylmethylphosphonium dimethylphosphate is shown. The reaction products are separated and characterized with 1H, 13C, 31P, 17O NMR spectroscopy, HD-MS, MALDI spectroscopy and XRD. It is shown that dimethylphosphate-anion is active in the reaction, and the addition of sulfur atoms occurs via the oxygen atom of dimethylphosphate-anion. It is found that a mixture of products is formed, which differ in the number of sulfur atoms in the chain. The assumptions were made about the mechanism of interaction of sulfur with tri-n-butylmethylphosphonium dimethylphosphate.

摘要 显示了在三正丁基甲基磷鎓二甲基磷酸酯存在下，S8 环打开并形成线性硫低聚物。反应产物用 1H、13C、31P、17O NMR 光谱、HD-MS、MALDI 光谱和 XRD 进行分离和表征。结果表明，磷酸二甲酯阴离子在反应中具有活性，硫原子的加成是通过磷酸二甲酯阴离子的氧原子发生的。发现形成了产物的混合物，其在链中的硫原子数不同。对硫与三正丁基甲基磷鎓二甲基磷酸酯的相互作用机制进行了假设。
