The polymer-bound palladium-catalyzed cross-coupling reaction of allylic alcohols with hypervalent iodomum salts to form carbun-ca~n bonds was achieved at room temperature under extremely mild and aqueous conditions even in the absence of base with very high activity in the Stille coupling reaction.
Arylation and alhenylation of 1-ethoxy-l-trimetylsilyloxycyclopropane with diphenyliodonium tetrafluoroborate and alkenyliodonium tetrafluoroborate were accomplished by slow addition of silyloxycyciopropane to iodonium salts in the presence of Pd( OAc) 2 (2 tool %) and DME/H20 (4 : 1) to afford ~ su
