The first example of a stable phenylsulfaneselenolate species was synthesized in a one-step process and isolated as the tetraphenylphosphonium salt [PPh4][PhSSe] as indicated by X-ray crystal structure analysis. Electrospray ionization mass spectrometry and NMR studies in solution showed the compound to enter a complex system of equilibria when dissolved. Computations suggested a high barrier for rotation around the C–S bond, indicating a π-system conjugated over the whole molecule. In general, the compound is closely related to the recently isolated [PPh4][PhS2] perthiolate salt.

苯硫基硒酸酯化合物的合成,分离和表征。
X射线晶体结构分析表明,稳定的苯基亚砜硒酸酯类物质的第一个实例是一步合成的,并分离为四苯基phosph盐[PPh 4 ] [PhSSe]。溶液中的电喷雾电离质谱和NMR研究表明,该化合物溶解后进入平衡的复杂系统。计算表明绕C–S键旋转的障碍较高,表明整个分子上共轭了一个π系统。通常,该化合物与最近分离的[PPh 4 ] [PhS 2 ]过硫酸盐密切相关。
