Triarylphosphines were converted to the corresponding oxides photooxidation as a novel method. In this study, cellulose was extracted from the plant and then oxidized by sodium metaperiodate. A gold complex was supported on this natural cellulose. Then, a gold complex on natural cellulose supported on FPS (FPS/Au(iii)) was synthesized for the reduction of phosphine oxides to corresponding phosphines with remarkable chemoselectivity. The morphology of FPS led to higher catalytic activity. FPS/Au(iii) NPs were thoroughly characterized using TEM, FESEM, FTIR, TGA, and BET.
三芳基膦通过光氧化转化为相应的氧化物，这是一种新方法。在本研究中，从植物中提取纤维素，然后用过碘酸钠进行氧化。在这种天然纤维素上负载金配合物。然后，合成了负载在FPS上的天然纤维素上的金配合物（FPS/Au(iii)），用于将氧化膦选择性地还原为相应的膦。FPS的形态导致了更高的催化活性。使用TEM、FESEM、FTIR、TGA和BET对FPS/Au(iii)纳米颗粒进行了全面表征。
