ruthenium(II)-catalyzed C−H bond alkylation with functional alkenes versus alkenylation has been developed depending on the acidic reaction conditions. Using this methodology, a few examples of desymmetrization of diarylphosphine oxides has allowed the formation of phosphorus derivatives containing three different substituents. After reduction of the phosphine oxide, this method allows the formation of aryl
根据酸性反应条件,已开发出一种快速改性芳基膦氧化物的方法,该方法涉及钌(II)催化的与功能性烯烃进行的CH键与烷基化反应而不是烯基化反应。使用这种方法,二芳基膦氧化物的脱对称化的一些例子已经允许形成含有三个不同取代基的磷衍生物。在氧化膦还原之后,该方法允许形成带有柔性侧链羧酸盐的芳基膦。
