The contents included the syntheses and molecular structures of organolanthanide complexes, such as tricyclopentadienyl,cyclopentadienyl halides, complexes containing Li-C σ bond,organohydrides, allyl-, cyclooctatetraenyl,tetraenyl-, neutral arene complexes and divalent complexes,and the application to the catalytic and organic reactions including hydrogenation,isomerization, polymerization,dehalogenation,deoxyenation and desulfuration.展开更多

Additionally, aryl amines and dihydroquinazolinones could be obtained selectively by controlling the electric current. Mechanistic studies suggested that the amination reaction likely involves an electrochemical oxidation-induced reductive elimination of a high valent rhodium intermediate, which led to the amination reaction even proceeding smoothly at room temperature.展开更多

Through this reaction, the synthesis of various pyrimidinones could be achieved. Of interest, it was found that the reaction was efficiently catalyzed by a novel, eco-friendly functionalized IL [C3SO3HDoim]HSO4, which could be reused for at least 7 times without significantly loss of catalytic activity. The reaction proceeded efficiently at 80℃ to afford the desired products in good yield(up to 96%). In addition, a possible mechanism that accounted for the IL [C3SO3HDoim]HSO4-catalyzed reaction was proposed.展开更多
