摘要合成了三氟甲烷硫代磺酸甲酯CF 3 SO 2 SCH 3,并通过13 C NMR,19 F NMR和振动光谱进行了表征。该结构研究得到MP2和DFT(B3LYP和MPW1PW91)计算的支持,这些计算揭示了理论结构对基集极化的强烈依赖性。理论数据表明,通过围绕S–S键旋转可以预测只有一个构象异构体gauche。使用总能量方案和自然键轨道分配方案研究了这种构象偏好。这些结果证明,电子离域,特别是LP S→σ∗ C(1)-S相互作用在含氧酸酯和硫代酸酯的反应性-结构连接中起着有趣的作用。记录并分配了气体和液体的红外光谱和液体的拉曼光谱。

The reaction of dimethyl sulfide with triflic anhydride leads to the formation of the corresponding dimethyl(trifluoromethanesulfonyl)sulfonium salt. The latter can be used in the mild oxidation of primary and secondary alcohols including unsaturated and natural ones to the corresponding carbonyl compounds in 34-75% yield. The reaction of various sulfides with triflic anhydride was studied. It was
