Carbonium ions are an important class of reaction intermediates, but their dynamic evolution is difficult to be monitored by in situ techniques under experimental conditions because of their extremely short life. Probably the most famous case is 2-no

Cleavage of aryl ether (Caryl–O) bonds is crucial for the conversion and value-added utilization of lignin and its derivatives, but remains extremely challenging under mild conditions due to strong Caryl–O linkages. In this study, the Caryl–O b

Tritylium salts have been used as Lewis acid catalysts in organic synthesis for a long time. In this work, we found that the Lewis acid catalytic activity of tritylium ions at the node of a tensile framework is significantly improved compared to that

The selective and high-yield production of α-olefins by alcohol dehydration is challenging because the isomerization and polymerization olefin products are more thermodynamically stable. In this study, we prepared a physical mixture of nano-sized al

The efficient conversion of xylose into lactic acid, especially with the novel contribution of C2 components, was revealed over the heterogeneous Sn-beta catalyst in water with a very high lactic acid yield of 70.0 wt% at 200 °C for 60 min. The 13C
