The generation of various β-chiral sulfones bearing chiral cyclic sulfinamides through photoredox-catalyzed sulfur dioxide insertion with asymmetric radical cyclization is described. This method features a broad substrate scope and excellent stereospecificity. Computational studies reveal that the dispersion interaction between sulfinyl group and CH2SO2Ph group plays a crucial role in the stereoselectivity control.

针对深部咸水层CO_2地质封存过程中流体的运移和压力的传递现象,利用美国Frio地区的CO_2咸水层封存试验实测数据,建立二维多岩相结构模型,模拟分析CO_2地质封存中CO_2注入阶段岩石孔渗性能的变化特征、岩层压力增加的变化特征以及CO_2羽流的演化规律。结果表明,超临界CO_2在驱替咸水溶液的过程中形成类似漏斗状的扩散晕,蒸发作用产生的盐沉淀主要位于井附近的单气相区,随着盐沉淀的增加,井周围的渗透率降低、压力积聚;盖层渗透性提高避免了储层内部出现过大压力,但却增加了泄漏的可能性。
