The arylation of allylsilanes catalyzed by a rhodium complex is described. In the presence of a catalytic amount of RhCl(CO)P[OCH(CF3)2]3}2 and Ag2CO3, allyltriisopropylsilane reacts with iodoarenes in m-xylene at 120 °C to furnish the corresponding C–H bond arylation products in moderate yields.

The rhodium-catalyzed decomposition of 2-(triisopropylsilyl)ethyl aryl- and vinyldiazoacetates results in the stereoselectiveformation of Z-allylsilanes. The transformation is considered to proceed by silyl-directed intramolecular C–H functionalization to form a β-lactone intermediate followed by a silyl-activated extrusion of carbon dioxide.
