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.

Pentacoordinate silicon compounds. Reactions of silatranes with nucleophiles
studied. Substitution involving cleavage of equatorial SiO bonds is always observed. Silatranes exhibit reactivity quite different from that of analogous trialkoxysilanes or anionic pentacoordinatesiliconcompounds.
