Transmetalation between lithium compounds and a significantly improved insoluble polymer-supported siloxane-transfer agent permits subsequent, efficient palladium-catalyzed cross-coupling reactions. The cross-linked polystyrene support facilitates product purification with excellent siloxane recycling.
