Palladium-Catalyzed Cross-Coupling of Aryl Chlorides with Arylsilatranes
摘要:
The cross-coupling reactions of arylsilatranes with readily available and inexpensive aryl chlorides were carried out in toluene/THF at 100 degrees C for 3 h in the presence of tetrabutylammonium fluoride as an activator for smooth transmetalation and catalytic amounts of palladium(II) acetate and XPhos.

摘要:
The cross-coupling reactions of arylsilatranes with readily available and inexpensive aryl chlorides were carried out in toluene/THF at 100 degrees C for 3 h in the presence of tetrabutylammonium fluoride as an activator for smooth transmetalation and catalytic amounts of palladium(II) acetate and XPhos.
The silylation of aryl and alkenyl iodides with hydrosilatrane in the presence of a rhodium(I) catalyst and DABCO provides the corresponding organosilatranes in good yield. The same catalyst system also enables the related coupling of hydrogermatrane.
